The company places great emphasis on innovation, R&D, and the high level of technical support that we provide to our customers. To this end, we have redesigned and upgraded our laboratories and invested in new analytical equipment for R&D and product quality control.
The greater accuracy of measurements and improved data gathering for statistical analysis are already contributing to refinements in product development and production process control.
Responding to and pre-empting the rapidly growing demand for our products, we have doubled our manufacturing capacity. We have also separated the production of each of our core product series into discrete, dedicated facilities for each range of products.
The upgrade to the production facilities included modification of existing structures on site, installation of new equipment, new forklift trucks, and the building of a small new unit to house one of the manufacturing facilities.
Lubricant Additives and Corrosion inhibitors
Brad-Chem Ltd is one of the UK’s largest independent lubricant additives and corrosion inhibitors manufacturers and suppliers. In recent years, Brad-Chem has achieved year-on-year increases in the number of industry standard testing approvals for its additives in low temperature and winter products.
Cold weather presents challenges for fluid performance, particularly for heat transfer and water based fluids, where thickening or freezing can occur, and also in automotive applications in which antifreeze properties are required for the engine coolants. Melt water from snow, ice and frost can also cause corrosion problems on roadside and trackside equipment. Brad-Chem works with customers to offer winterization and low temperature solutions for corrosion inhibition / rust prevention and low temperature lubrication solutions with the greatest efficacy and the minimal environmental impact. Contact us for more information on our winterization solutions.

Innovative new products
Brad-Chem has recently developed new corrosion inhibitors for high alkali systems and for acid conditions. We now have a complete range of multi-metal corrosion inhibitors for hydrochloric, sulphuric, phosphoric, sulphamic, acetic, citric, and tartaric acids. In addition to our existing range of corrosion inhibitors for neutral to slightly alkaline conditions, we now have a multi-metal corrosion inhibitor that shows excellent weight loss corrosion reduction on even the most difficult metals in high alkaline conditions.
High alkaline corrosion inhibitor
Many highly alkaline cleaners are very corrosive to certain metals, particularly to aluminium alloys. Brad-Chem 512 has been developed as a multi-metal corrosion inhibitor for high alkali cleaners and other high pH applications. In tests, this product has shown < 80% inhibitor efficiency in reducing weight loss corrosion of aluminium at pH 14 and good surface finish.
Acid Corrosion inhibitors
Recent product development efforts at Brad-Chem have led to us completing our range of corrosion inhibitors for acid cleaning and pickling, with new multi-metal corrosion inhibitors developed for hydrochloric, sulphuric, phosphoric, sulphamic, acetic, citric, and tartaric acids. We currently have a number of readily biodegradable corrosion inhibitors available for multi-acid and multi-metal applications. We have also recently developed Brad-Chem 593 for sulphuric, phosphoric, sulphamic, citric, and tartaric acid applications, which completes our range.

Comparing Oil Tackifiers
Comparing oil tackifiers was very hit and miss, prior to Brad-Chem entering into the market. When we developed our UK market-leading product Flowtac 2000, we devised new test methods to prove the performance. This product continues to gain approvals and aficionados worldwide. For many lubricant blenders, testing comprised dipping gloved fingers into tacky additized oil and visually comparing the stringiness of the oil. This method was hardly scientific and was inconsistent at best.
The Brad-Chem technical department devised reproducible tests to determine the increase in oil retention on a rotating spindle that results from adding an oil tackifier to the oil. In this way, it was finally possible to reliably compare tackifying power of competing oil tackifiers, with good reproducibility of results.
Brad-Chem Oil Tackifiers
Brad-Chem Ltd offers its UK market leading product Flowtac 2000 for mineral oil based applications. Our “clingability” and “stringability” tests consistently show that this product users can halve the treat rate compared to that of leading competitors. Furthermore, as its name implies, another major advantage of Flowtac 2000 is that it is less viscous than many competitor products. Moreover, due to the lower viscosity, blenders find that it is easier to handle. Consequently, many blenders can use a pump to transfer Flowtac 2000.
Alternatively, we offer Contac 2000 for HX-1 incidental food contact applications. Contac 2000 is based on the same technology as Flowtac 2000. This product gives identical tacky performance, with the additional advantage that all components are NSF approved for incidental food contact applications.
Vegetable Oil Tackifier
Some lubricant manufacturers use Vegetable oils, such as rapeseed oil, to manufacture industrial lubricants. These oils are kinder to the environment than mineral oil. Brad-Chem offers Biotac oil tackifier for rapeseed and other vegetable oil based lubricants.
Brad-Chem Ltd manufactures corrosion inhibitors, speciality lubricant additive packages and solid lubricant dispersions. We also distribute for Climax Molybdenum, Nyco and BRB International. The product ranges that we supply from these principals compliment and complete the solutions that Brad-Chem can offer to the lubricant manufacturing, forging, forming, and metal cleaning industries.
BRB INTERNATIONAL BV
BRB International BV manufacture lubricant additive packages for driveline/automotive, off-road/agricultural and mining applications, and viscosity index improvers / viscosity modifiers. BRB have been gaining customer approvals for their low sulphur automotive gear oil package Petrolad 336; this product can provide limited slip without the need for a separate limited slip package. The automatic transmission fluid (ATF) additive package Petrolad 743N can be used at lower treat rates than some of the leading competitors for similar or better performance standards. Petrolad 8363 is a UTTO tractor oil additive with excellent wet braking performance. We also supply PCMO and HDDO cascade packages and shear stable VI improvers for a wide range of applications.
Climax Molybdenum manufactures the highest quality molybdenum products in the world. Molybdenum disulphide is a solid lubricant and we are able to supply in a range of particle sizes. Molybdates are used as corrosion inhibitors, catalysts, mineral supplements, and fertilizer components. For many of these applications, the use of consistent high quality molybdate is of paramount importance since the consequences associated with product quality issues are expensive and quite often disastrous and many of the grades available elsewhere are not suitable for some of the applications. As the distributor for Climax Molybdenum, Brad-Chem Ltd supplies the highest and most consistent quality sodium molybdate, ammonium dimolybdate, ammonium heptamolybdate, and molybdic oxide for all of your catalyst, fertilizer, mineral supplements, and corrosion inhibitor requirements.
Nyco manufactures speciality synthetic esters and synthetic ester based lubricants and greases for a wide range of industrial applications. The advanced technologies of Nyco products and the level of technical support that Brad-Chem and Nyco can offer to customers make them the perfect partner for specialist lubricant blenders. Nyco’s Green range are high performance speciality esters and lubricants with a very high level of biodegradability and responsibly sourced renewable carbon, with many products listed on the Lubricant Substances Classification (LuSC) list. Nyco also offer very advanced high temperature thermally stable esters and lubricants for a number of applications including high temperature chains and HFDU fluids, and food grade esters with NSF HX-1 / H1 approvals.

Corrosion Inhibitor Approvals
We are now into December and the requirement for the use of corrosion protection in winter products is evident by the sales and approvals. The market and environmental pressures mean that the need to minimise corrosion is very important. You can reduce maintenance and downtime by using a winter product containing a corrosion inhibitor. In addition, our winter products corrosion inhibitor products also improve equipment life, creating even more savings.
Brad-Chem has developed corrosion inhibitor packages to help manufacturers and formulators of winter products to gain product approvals in the following markets:

Brad-Chem offers corrosion inhibitors for multi-metal winter product applications. Moreover, we can also offer a corrosion inhibitor for steel, as well as corrosion inhibitors for aluminium, magnesium alloys, copper and yellow metals.
Graphite and Molybdenum Disulphide Dispersions
Brad-Chem Ltd is continually innovating and one of our main areas of expertise is in solid lubricant dispersions. We can offer a wide range of graphite dispersions, molybdenum disulphide dispersions and also some mixed dispersions containing both lamellar solid types.
Applications for solid lubricant dispersions
Solid lubricant dispersions form a low friction coefficient solid layer on surfaces, which gives boundary lubrication in extreme pressure situations such that the layer will continue to lubricate even when there is no liquid lubricant between the surfaces of the moving parts. This boundary lubrication is important in high temperature applications such as metal forging and forming, where the oil or water component of the dispersion can either burn off or evaporates during the processing.
Solid lubricant dispersions are also used in high temperature chain lubrication where the temperature may be too high for conventional mineral oil type lubricants. Sometimes the solid lubricant can be applied using a water- or volatile solvent-based dispersion, which evaporates leaving the solid bound to the chain or other surface type; this is called dry film lubrication. Dry film lubricants can be applied by dipping, brushing, or spraying and they are often aerosolised.
Concentrated dispersions of solid lubricants in oil or synthetic oil types are useful for adding solid lubricants to industrial or automotive lubricants to improve the extreme pressure performance for speciality applications. The small particle sizes and the presence of appropriate dispersing agents help to ensure that the resulting oils remain stable.
Some aerospace lubrication applications have to work in a vacuum or in a thin atmosphere in which a conventional lubricant would simply evaporate away; these applications require molybdenum disulphide as the solid dry film lubricant. Unlike graphite, which needs adsorbed water molecules to enable the layers or lamellae to slide past each other, molybdenum disulphide is an inherent lubricant and can lubricate without adsorbed water molecules.
Innovation in solid lubricant dispersion
At Brad-Chem, our in-house technical department are continually developing new and innovative products in the areas of corrosion control, lubricant additives and solid lubricant dispersions. We work with customers to solve problems and to unlock new applications. For more information on our solid lubricant dispersions please see our knowledge base or contact us.
Additives for Biodegradable Lubricants
Brad-Chem Ltd develops and manufactures lubricant additive packages that can be added to suitable base oils in order to make biodegradable industrial oils, such as hydraulic oils, compressor oils, gear oils, and chain oils. We continue to develop new and innovative lubricant additive packages for biodegradable and biorenewable oils, and we have now developed an all-biodegrdable, low toxicity labelling additive package for biodegradable and biorenewable base oils for total loss applications.
In addition to our additives, we also distribute Nyco Synthetic Esters. The Nyco esters range includes many esters that are biodegradable and non-toxic, many of which enable lubricant blenders to comply with the European Ecolabel and the LuSC list. A lot of the Nyco esters also have a significant proportion of their total carbon content coming from renewable sources.
For incidental food contact applications we can offer Brad-Chem HX-1 lubricant additive packages that can be added to suitable H1 or HX-1 approved base oils to produce biodegradable lubricants for incidental food contact.
Additives for Biorenewable Oils
Biorenewable oils are lubricant base oils of recent biological origin; they are distinguished from biobased material in that they are naturally occurring and 100% of their carbon is from biorenewable sources. The main biorenewable base oils are vegetable oils. Brad-Chem manufactures lubricant additive packages specifically designed for the challenges of using biorenewable base oils to manufacture industrial lubricants that perform.
Further information on our existing lubricant additive package offering for making industrial lubricants from biorenewable base oils can be found here and details of our oil tackifier Biotac for biorenewable vegetable base oils are available here. You can also contact us for further information, technical data, material safety data sheets (MSDS) and samples.
In addition to our existing offering, we have developed a new, all-biodegradable lubricant additive package for ecofriendly, biorenewable base oils to make lubricants for total loss applications. Contact us for further information.
Additive packages for biorenewable and biodegradable industrial oils continues to be a strong focus of our research and development and we are working to produce innovative industrial lubricants based on these base oil types.
WHAT ARE THE APPLICATIONS OF CORROSION INHIBITORS?
Corrosion inhibitors are used in any application in which metals are in contact with water, or applications in which water may come into contact with metals. Most of these applications are encountered by industrial cleaning, metalworking fluids manufacturers and preventive maintenance professionals.
The term corrosion inhibitor is often used interchangeably to describe a number of very different products and, therefore, it is important to define to which type we are referring. For the purposes of this article, the term corrosion inhibitor will only refer to corrosion inhibitors that are used in the liquid phase (i.e. not those incorporated into coatings, since this is a very different industry).
The range of applications in which metals are in long term contact with liquids is vast and ranges from in-can applications for liquids stored in tins or aerosol cans, through water blasting/ pressure cleaning applications, all the way through to industrial lubricants and heat transfer fluids. Parts washing and impregnation, hard surface cleaning, and industrial cleaning, and anywhere where water is left to dry on a metal surface can also cause either surface discolouration, or flash rusting. Corrosion inhibitors are added to the cleaning products and the rinse water to inhibit flash rusting or discolouration in cleaning, parts washing, and impregnation applications.
HOW DO I SELECT A CORROSION INHIBITOR?
How well any given corrosion inhibitor performs is determined by the conditions under which it is operating. In order to select the most appropriate corrosion inhibitor and the optimal dosage for any given fluid, you first need to know the following information about the operating conditions:
• Is the fluid water-, oil-, or solvent-based?
• What is the pH of the fluid?
• Are there any dissolved corrosive salts?
• Which metals are affected by this fluid?
• For how long is the fluid intended to be in contact with the metal?
• Is flash rusting likely to be an issue while the metal is drying?
The answers to these questions will clarify the choice of corrosion inhibitor. For example, if the issue is flash rusting as water from blast cleaning dries on the metal surface, then the ideal corrosion inhibitor is Brad-Chem 563.
Clearly, corrosion inhibitors that are soluble in hydrocarbon solvents or oil are likely to have very limited solubility in water based fluids, a corrosion inhibitor designed for alkaline systems is unlikely to be compatible with or effective in acid systems, and so on.
WHY DO I NEED A CORROSION INHIBITOR?
Worldwide, the annual costs resulting from corrosion has been reported at US $2.2 trillion, which is over 3% of the world’s GDP. Corrosion inhibitors can reduce the damage caused to equipment as a result of corrosion, therefore reducing equipment replacement and maintenance costs.
WHY CHANGE FROM MIXED ACIDS?
The recently announced closure (Lubes ‘N’ Greases, February 2016) of the Victoria plant in Texas threatens the ongoing supply of Corfree M1, the mixed acid traditionally used for corrosion inhibition in metalworking fluid formulations.
In addition, costs associated with increasing global regulatory pressures are also having a negative effect on the supply of this and similar mixed acid products. The dusty nature of these solid products means that many lubricant blenders find they are difficult to handle and can be unpleasant to work with in a production workplace environment.
IS THERE AN ALTERNATIVE TO CORFREE M1?
Corfree M1 and other mixed solid acid products need to be neutralised in order to solubilise them so that they can be used as a corrosion inhibitor in metalworking fluids. This generally means that they must always be used as the reaction product with at least one other raw material or intermediate and, this reaction is often carried out in situ during the manufacture of the metalworking fluid or concentrate.
Brad-Chem can offer pre-neutralised alternatives to these mixed acid products that are carefully balanced to give optimum performance. These cost-effective liquid products are easy to handle and non-dusting in a metalworking fluid production environment and they can be used as an alternative to both the mixed acid products and the bases that are traditionally used to neutralise them. The ease and speed of mixing can also reduce turnaround cycle times and increase manufacturing throughput.
WHAT ABOUT UNUSUAL APPLICATIONS?
Our Brad-Chem technical and R&D team can work with metalworking fluid producers to develop bespoke formulations that can replicate or improve upon existing formulations. This work can be carried out under conditions of non-disclosure and we have a reputation for providing technical support and working with customers to develop individual solutions.
Similar products can also be used in parts washing, industrial cleaning, and preventive maintenance fluids Contact us for further details.
WHAT IS SUSTAINABILITY?
Sustainability encompasses a range of activities and product choices that minimise environmental impact to try to ensure that resources and quality of life can be maintained for future generations. Activities that help to prevent the unnecessary depletion of natural resources and maintenance of quality of life are those such as reduction of waste, recycling, composting, selection of biodegradable materials, and the selection of low toxicity and low eco-toxicity materials. The goals of sustainable product development for lubricant manufacturers is to develop easily renewable or recyclable materials that are highly biodegradable and that have the lowest possible toxicity to human health or to ecosystems, whilst still maintaining their effectiveness for purpose.
WHAT ARE THE COMMERCIAL ADVANTAGES?
This is a timely question. The environmental case for sustainability is practically incontrovertible, with the consensus of expert opinion being that greater sustainability delivers improved health and quality of life for all. However, what is the purely business case now that the prices for the largely non-sustainable commodity materials are generally depressed, whereas most of the more sustainable alternatives have shown no such price decrease? Undoubtedly, most businesses encounter many marketing claims that sustainable products will deliver savings over the long term, based on assumed energy use and unit costs and (sometimes optimistic) projections. Rather than add to the volume of such literature, this news item will, instead, simply clarify the commercial advantages of using products that have a high level of biodegradability and renewable carbon to make lubricants.
WHY BIODEGRADABLE LUBRICANTS?
A commonly held misconception about biodegradable lubricants is that the disposal costs are lower; however, in most regions, this is not the case and biodegradable lubricants are generally disposed by incineration, the same as other waste oil. The advantage of using biodegradable lubricating oil is related to regulations regarding spillage.
Lubricant oil spillages can happen at any time. Prevention measures to rapidly clear up a spillage before it enters the water courses or the soil are usually adequate for very small spills. However, just 1 litre of oil is enough to pollute 1,000,000 litres of water. Water or soil pollution can be absorbed by green plants and, further through the food chain, it can also adversely affect human health; soil pollution can also adversely affect the value of real estate.
Increasing regulation has resulted in fines, prosecutions, and increased administrative costs to polluters in a number of industries. In some industries, the regulatory costs associated with spillage of biodegradable and non bioaccumulating products are much lower than those incurred as a result of spillages of non biodegradable alternatives.
WHY RENEWABLE LUBRICANTS?
In most regions, all lubricant oils are disposed by incineration, which results in the release of combustion products (chiefly carbon dioxide and water) to the atmosphere. Carbon dioxide is taken in and used by green plants in photosynthesis and, in turn, some of these green plants are the main source of many of the components of renewable lubricants. National and international targets for the limitation of carbon emissions are a focus for both national climate change committees and international bodies such as the United Nations committee on climate change.
Presently, some of the most potentially polluting industries are subject to climate change levy based on carbon emissions, which can significantly affect their costs. For industries in which these costs are significant, there is a drive towards carbon neutrality. Full carbon neutrality is when an entity achieves zero net carbon emissions, i.e. when its activities remove as much carbon from the atmosphere as it emits. The use of renewable lubricants that are based on components obtained from green plants, which absorb carbon dioxide from the atmosphere, can be offset against carbon emissions.
Brad-Chem manufacture speciality industrial lubricant additive packages. These are balanced lubricant additive packages that can be added to vegetable base oils and various synthetic base oils in order to manufacture lubricants with a high percentage of renewable carbon, and biodegradable lubricants. We can also supply a range of synthetic Brad-Chem biodegradable lubricants for private label, and synthetic biodegradable base oils such as the Nycobase synthetic esters (many of which contain a high proportion of renewable carbon), and PAOs.
BRAD-CHEM DEVELOPS NEW CORROSION INHIBITOR FOR METALWORKING FLUIDS AND CLEANERS
Further to the withdrawal of Corfree M1, Brad-Chem Ltd.has developed an easy-to-handle liquid alternative corrosion inhibitor for the cleaning and metalworking fluids markets.
In order for Corfree M1 to be used as a corrosion inhibitor in water based fluids, this material needed to be neutralised. We know that in some formulations the mixed acids were neutralised to approximately neutral pH (ca. pH 7), whereas in other formulations Corfree M1 was overbased to mildly alkaline pH in end use.
Our newly developed multi-metal Brad-Chem 588 is a similar mixture of acids, neutralised to approximately neutral pH which can be used as a direct replacement for the Corfree M1 and the bases that are commonly used to neutralise it to neutral pH liquid corrosion inhibitor.
If a replacement for an overbased formulation is required, this can be achieved either by the addition of Brad-Chem 588 together with a small amount of a suitable base, or contact us for bespoke solutions to your reformulation needs.
SUSTAINABLE NYCO GREEN ESTERS
Nyco’s Green range is a selection of synthetic esters and finished lubricants that are able to fulfil the requirements of environment labels. Indeed, many of these products are listed on the LuSC list. LuSC listing means that they are suitable for use in Ecolabel products and marine lubricants that conform to the United States EPA Vessel General Permit (VGP) requirements.
High levels of renewable carbon and biodegradability are both very important goals. Nyco are committed to sustainability and believe that renewable carbon from crops should be responsibly sourced. This means that the renewable carbon components are not produced at the expense of biodiversity, important ecosystems, or excessive use of land that could otherwise be used to produce food.
Nyco vet their raw materials streams to ensure that renewable carbon components are responsibly sourced from certified sustainable sources.
Additionally, Nyco have recently developed a new analogous range of synthetic esters that are biodegradable but without the high levels of renewable carbon required for environmental labels.
Due to the limited supply of sustainably sourced renewable carbon components, esters made with such components can be costly. So, in applications where the demand is only for a high level of biodegradability, Nyco can supply more cost effective alternatives.
FOOD GRADE NYCO ESTERS
Nyco offer a range of products for lubricant applications with incidental food contact.
The range of Nycobase esters that are NSF approved for incidental food contact (H1) has recently increased. This includes the addition of a new high temperature stable food grade ester Nycobase 32506 FG.
Low pour point and highly biodegradable and high renewable carbon food grade esters have also been added.
A newly developed, readily biodegradable food grade ester, Nycobase 30409 FG has been developed. This new product benefits from a low pour point, high flash point and good lubricity. The growing range allows for multiple formulary options.
There is also a very high viscosity food grade ester suitable for food grade grease manufacture.
WHY CORROSION INHIBITORS & ADDITIVES IN WINTER PRODUCTS?
In winter, the snow, ice, and melt water create their own unique challenges for automotive, rail, marine, and air transport and infrastructure. Industrial functional fluids can also be affected; because, falling temperatures can cause micro wax formation in hydrocarbons and vegetable oils, or freezing in water based fluids.
Brad-Chem manufactures corrosion inhibitors and lubricant additive packages, including additive components for winter products. We can supply corrosion inhibitors specially designed for use in winter products, and solutions to low temperature issues in mineral, synthetic, and vegetable oil based fluids.
WHY CORROSION INHIBITORS FOR WINTER PRODUCTS?
In order to achieve low temperature performance, winter products are often formulated differently to products that are used at ambient temperatures only. To maintain winter performance freezing point depressants are added to fluids and these can change the corrosiveness of the fluid.
Most commercial and industrial preventive maintenance fluids and deicers are extensively tested against a range of criteria to ensure that they fulfil their purpose, while ensuring the integrity of valuable items are equipment.
Brad-Chem corrosion inhibitors can help you to ensure that your winter products perform well in corrosion inhibition tests. Our experienced technical team can also help you to ensure that your winter product formulation passes requisite international standards.
CAN I REFORMULATE MY WINTER PRODUCT TO REPLACE CORFREE M1?
Brad-Chem has developed new corrosion inhibitor solutions to replace Corfree M1 and bases in cleaning applications, metalworking fluids, and winter products.
Contact us to find out how we can help you to replace Corfree M1 in your winter products.
WHY LUBRICANT ADDITIVES FOR WINTER PRODUCTS?
Lubricants and associated products that need to function at low temperatures need specialized lubricant additives or synthetic base oils with good low temperature properties.
Two of the main issues affecting both hydrocarbon fluids and mineral, vegetable, and synthetic oils are cold flow and cold filter plugging. Brad-Chem has a high degree of technical know-how and can offer a range of solutions; contact us to see how we can help you with your winter product formulations.
HOW DOES TECHNICAL SERVICE SET BRAD-CHEM APART?
Brad-Chem Ltd has more than a quarter of a century of experience of technical service, innovation, product development, and expertise in chemical regulation and international standards.
Since its establishment, the company mission has been to improve the market availability of innovative, cleaner and better performing technologies in lubricant additives, and corrosion inhibitors for the industrial cleaning and maintenance fluids manufacturing sector.
Our commitment to research and product development ensure that we continue to develop new and bespoke optimal solutions for our customers. We also assist customers with their product development through technical service to ensure we deliver the most appropriate additive recommendations, advice, and regulatory compliance.
CAN BRAD-CHEM HELP ME WITH PRODUCT OPTIMISATION?
Whether you are developing a new product or replacing a component of an existing formulation, it is important to ensure that the new development is viable. The answers to three questions determine viability of a new product development:
• Is there a sufficient market?
• Does the new product perfom better than existing competitors?
• Is the cost of the new product viable?
Product optimisation can help to ensure that your new product is either better than the competitors or that you can offer better cost at like-for-like performance levels. In order to demonstrate better effectiveness, the performance of a product must be tested against the alternatives.
Brad-Chem works with customers to ensure that, between us, we select the most appropriate additive recommendations from our product range. We provide samples for testing in the customer’s product development and technical support on how best to use our products.
Our technical team can also test a range of our additives in a customer formulation against the customer formulation without our additives or against competitor products to determine the viability.
We ensure a smooth transition from product development to product realisation by providing technical and regulatory information on all of our products and ongoing sales support and technical service.
WHAT MAKES AN OIL INTO A LUBRICANT
Brad-Chem Ltd is the UK’s largest independent manufacturer of lubricant additive packages, supplying to lubricant blenders worldwide.
Lubricant blenders formulate lubricants by taking a base oil and adding additives. Additives serve several functions; protecting the oil itself against oxidation and degradation, and protecting moving parts against extreme pressure, wear, loss of lubrication, and corrosion.
Loss of lubrication can occur as a result of evaporation of the oil at high temperature, by boundary conditions under extreme pressure, or by oil run off. The last of these can be mitigated by addition of a tacky additive, such as the market leading Flowtac 2000. Tacky additives will be discussed in a later news item.
Oil on its own is not sufficient as a lubricant for the vast majority of applications. Even the simplest applications generally require a formulation based on a base oil plus an appropriate combination of additives.
WHY USE LUBRICANT ADDITIVE PACKAGES?
Formulating a lubricant with the right combination of additives at the right levels is a difficult product development challenge. The mixture of additives and base oil must meet the performance requirements of the both the application itself and of any international standards or OEM specifications required by the end user.
For a speciality industrial applications, such as H1 lubricants with incidental food contact, or to the requirements of an environmental standard, there are additional restrictions of the permissible additive components and base oils.
Many international standards specify minimum pass level requirements for a battery of expensive and often long term tests. New development formulations can often pass most of the tests only to then fail at the last hurdle and require reformulation and retesting. Repetitive retesting and reformulating can become very costly for the formulator.
Additionally, some additives compete with each other for access to surfaces and, therefore, have to be balanced to the right addition levels so that both types can perform their required roles.
Using a suitably formulated lubricant additive package takes the guess-work out of formulating. Adding a liquid additive package to an oil can reduce or eliminate the need for heating that would otherwise be required for the dissolution of solid individual additives.
Brad-Chem lubricant additive packages are easy-to-handle liquid blends of lubricant additives. They are formulated to meet the requirements of speciality industrial compressor oil, hydraulic oil, and gear oil applications when added to a wide range of different base oil types. We can offer products for making vegetable oil based industrial lubricants as well as for mineral and synthetic oils.
MOLYBDENUM DISULPHIDE AND MOLBDATES
Molybdenum disulphide (or Molybdenite) is the naturally occurring ore of molybdenum metal. Climax Molybdenum mines this ore with the highest conditions of worker safety and refines it to exacting standards of purity and particle size distribution.
Molybdates are chemical products made from molybdenum disulphide. They are made by swapping the sulphur atoms for oxygen atoms to form molybdic acid / pure molybdic oxide and subsequent basification.
Depending on the base used and the conditions used in the basification, a variety of molybdates can be produced. The most commonly used molybdates are Pure molybdic oxide, sodium molybdate dihydrate, ammonium dimolybdate, and ammonium heptamolybdate tetraydrate.
WHAT ARE THE USES OF MOLYBDENUM DISULPHIDE?
Molybdenum disulphide (MoS2) is primarily used as a solid lubricant. It can be used as a dry film lubricant or as a dispersed lubricant in a suitable carrier. In both cases, the lubrication is provided by stacked plate-like layers of molybdenum disulphide that slide over each other.
Dry film lubricants are lubricants that prevent extreme pressure and wear damage to moving parts without a liquid component present. The molybdenum disulfide for this application is usually dispersed in a volatile solvent and the solid film is usually applied to the parts by spraying, brushing or dipping and allowing the solvent to evaporate.
Solid lubricant dispersions comprised dispersed solid lubricant in oil or water. The oil may provide some lubrication under low load conditions, but the molybdenum disulphide provides the main lubrication and sometimes the only lubrication when very high pressures are applied. These products are useful for metal forging, metal forming, and moulding metal parts
Unlike graphite, molybdenum disulphide is an inherent lubricant and does not require water between its molecular layers in order to provide lubrication. For this reason it can be used in thin atmospheres or even in the vacuum of outer space.
WHAT ARE THE USES OF MOLYBDIC OXIDE AND MOLYBDATES?
Molybdic oxide is used as a component of some types of steel, as a water treatment chemical and also as a reagent for the manufacture of other molybdenum compounds. The primary function of molybdic oxide as a component in steel and as a water treatment chemicals is the prevention of corrosion.
Molybdates are also very good corrosion inhibitors for steel and aluminium and these products are also used in water treatment applications. In particular, sodium molybdate is often used in boiler and heating system water treatment chemical formulations. Another use of sodium molybdates is a bioavailable source of molybdenum, particularly in the formulation of fertilisers for leguminous crops.
Ammonium molybdates are also sometimes used as corrosion inhibitors and sometimes used as a bioavailable source of molybdenum. These materials are also used in catalysis in industrial chemical manufacture.

SOLAR AND GROUND SOURCE HEATING
Corrosion is a serious issue for providers of solar and ground source / geothermal heating.
In solar and ground source heating systems, corrosion can occur; because, heat transfer fluid transfers the heat energy through metal pipes from the heat source to the radiators. Normally, the heat transfer fluid medium is based on either water, water/glycol mixture, or water containing dissolved salts.
The heat transfer fluids or solar and geothermal systems are similar to those for cooling systems and air conditioning systems. Such systems generally comprise a pump, metal pipes, and fins, or radiators to take heat energy away from a heat source and to radiate that energy back to the environment elsewhere.
Very often, heating systems are multiple component in nature and the pipe work is generally soldered, welded, or bolted together. This means that an uninhibited heat transfer fluid can cause corrosion to a variety of different metals.
INHIBITING CORROSION IN HEATING PIPES
It is difficult to completely prevent metals from corroding, other than by regularly applying an impermeable coating. A coating of this kind is usually impractical for the insides of heating and cooling pipes, due to the effects that hot heat transfer fluid can have on paint.
There are several ways in which a maintenance engineer can reduce corrosion by geothermal / solar fluid:
- Add a multi-metal corrosion inhibitor, such as Brad-Chem 552, to the fluid
- Try to find a less inherently corrosive alternative fluid
- Replace metal pipes, pumps & fittings with less susceptible parts
In most cases, owners or engineers add a corrosion inhibitor; this is the simplest, most cost-effective method. Brad-Chem 552 is a multi-metal corrosion inhibitor for a wide range of applications. These applications include solar / geothermal heating, antifreeze, engine coolants, and incidental food contact.
We supply our products worldwide. Contact us for further information. You can find our distributors in your region via our distributors page. If you are unable to find a distributor in your territory, contact us.
ECOLABEL COMPLIANT ADDITIVE PACKAGE NEW PRODUCT LAUNCH
Brad-Chem Ltd has developed a new EU Ecolabel compliant lubricant additive package. Add Brad-Chem 353 to rapeseed oil, synthetic esters, PAOs and other biodegradable base oils to make lubricants and greases. We recommend this product for the manufacture of industrial lubricants such as gear oil, hydraulic oils, and chain oils, etc.
Brad-Chem develops and manufactures speciality lubricant additive packages for supply to specialist lubricant blenders worldwide.
The Ecolabel is a voluntary scheme established in 1982 that producers can use to show that a product meets a Europe-wide environmental standard.
As the distributor for Nyco Esters, Brad-Chem can also supply compliant base oils. Simply add our liquid, easy to handle additive package to the base oil and blend to make the lubricant.
All components are also compliant with Environmentally Acceptable Lubricants (EAL) for marine applications.
WHAT ARE THE ADVANTAGES
Despite the growth in consumer demand for more eco-friendly products, marketing claims about green credentials are often worded with subtle differences from one manufacturer to the next. These nuances, although small, can sometimes mean very different things.
Research indicates that consumers care about the quality and validity of the information that they receive regarding the environmental impact of their product choices. Studies also suggest that the existence of too many schemes and some poorly regulated labelling schemes causes confusion and reduces trust .
The European Ecolabel scheme easily identifies lubricants made with components vetted for environmental acceptability. This presence of this label also means that the manufacturer has determined the biodegradability and bioaccumulation potential of the product. This information can assist consumer choices.
The advantages for manufacturers are that Brad-Chem 353 is a liquid, easy to handle, and well balanced additive package that lubricant blenders can add to a suitable base oil to make a range of lubricating oils.
NEW PRODUCT RELEASE DATE
The new product launches on 7th March 2017, and technical data sheets, material safety data sheets are available on request. Telephone +44 (0) 1942 261024 and ask for technical if further details are required.
For further information on our products contact us, or follow us on Twitter for further updates. To find distributors in your region, see our distributors page or contact us if not listed.
PRODUCTION LINES AT HIGH TEMPERATURE
Manufacturers who use machinery driven by chains that operate at high temperature can increase throughput by improving cycle times, reducing downtime, or adding more production lines. Usually, the requirement to increase throughput arises because of an increase in demand. Moreover, producers can not always establish if the increase is a spike or a sustainable market growth.
Reducing cycle times is possible if machinery can run faster without loss of process integrity. This is achievable if the product does not need to remain in the oven for longer periods, or if it is safe and advantageous for operatives to increase the temperature. To run the chains faster, manufacturers must use a lower viscosity chain oil and, usually, there is a lower viscosity limit, below which the lubricant film breaks catastrophically
In order to reduce downtime, operators need to increase the service life interval between stoppages for maintenance of the chain and the lubricant. This can be achieved by careful operation and by selecting a superior high temperature chain lubricant that will give a longer interval between stoppages for service and maintenance.
IMPROVING CHAIN LUBRICANT SERVICE INTERVALS
Typically, a chain oil designed for use at elevated temperatures consists of a thermo-oxidation resistant base oil and, most important of all, a high temperature lubricant additive package.
Good examples of base oils include synthetic esters, poly alpha olefins, and silicone oils. Brad-Chem 336 is an example of a typical additive package; however, Brad-Chem have developed several speciality packages for this application, including H1 incidental food contact,additive packages H2 packages and higher temperature and longer service life packages.
The technology in this field has developed rapidly in recent years and Brad-Chem is at the forefront of new innovations. We have developed ranges of food grade and top tier synthetic ester based lubricants or private label with superior combinations of properties.
In the course of these developments, we have also developed our technical expertise in this area. Furthermore, there is no single solution for all applications ; it is vital to tailor the selection of additive package and base oil to the specific application and conditions.
We can offer the Nycobase esters, additive packages, and, also, fully formulated blends for private label. Contact us for further information on our high temperature lubricant additive packages, base oils, and lubricants.
IN-CAN & LIGHT ALLOY CORROSION
Aerosol manufacturers and suppliers often find that water based products cause in-can corrosion in the cans during long term storage. Often, suppliers only discover this issue when some of the cans develop holes and start leaking.
Usually, the problem of leakage is limited to a small number of cans from any given batch of product. However, suppliers can sustain reputation damage when this type of corrosion happens in a can that has been sent to a customer.
Light alloys are those that contain the less dense metals such as aluminium and magnesium. Typically, vehicle applications use these alloys to reduce the weight and increase fuel efficiency. Moreover, aerospace applications frequently use these types of alloys.
Corrosion of vehicles and, in particular, aeroplanes can have serious safety implications for passengers. It is, therefore, of the utmost importance to inhibit corrosion of light alloys in these applications.
Brad-Chem 583 is a corrosion inhibitor for advanced light alloys and for in-can corrosion.
This inhibitor can be used for in-can corrosion inhibition, or for Rail, Automotive and Aerospace applications where water is in contact with metal. For example, Brad-Chem 583 is a component for aeroplane cleaner or for train cleaning products. This product also gives excellent protection against aluminium staining in cast aluminium parts washing and impregnation.
Brad-Chem 583 also gives multi-metal protection for iron, steel, copper and yellow metals. For in-can applications, this product is very good for aluminium cans and also for tin-plate. All of the components of Brad-Chem 583 are FDA approved for incidental food contact.
For further information, see our knowledge base or contact us and speak to our technical team. For information on other applications, please check our previous news items or search our products pages. You can search by sector & use applications or by product type.
WHAT IS FLOWTAC 2000?
Flowtac 2000 is the market leading tacky additive for mineral oil based lubricants from Brad-Chem Ltd.
Our reputation for proven excellent performance is well known throughout the lubricants industry. Brad-Chem also has a reputation for reliability of supply, with our history of consistent supply since 1988.
Flowtac 2000 is a tacky additive. Lubricant blenders add the tacky additive to lubricating oils to make the oil stick to moving parts. End users of these oils benefit; because, it reduces loss of lubrication by dripping or fling-off, and it reduces oil mist in metalworking fluid applications.
WHAT IS FLOWTAC 2000 USED FOR?
Lubricant blenders use Flowtac 2000 to manufacture the following products:
- Slide way oils
- Chain oils
- Wire rope lubricants
- Rock drilling oils
- Textile lubricants
- As an anti-mist agent in metalworking fluids
WHAT GIVES FLOWTAC 2000 ITS GREAT REPUTATION?
The performance is the most important property of a tacky additive for mineral oil. The tacky additive must be able to retain as much of the oil as possible on the moving parts without adversely affecting the friction coefficient.
Flowtac 2000 imparts to the lubricant the best possible combination of adhesion of the oil to part and cohesion within the oil itself, ensuring that it remains in place. We have proven the adhesion by developing cling tests that show the increased mass of oil remaining on a part after a period of rapid spinning. Furthermore, we have also developed string tests that show the improved cohesion of the oil to itself.
Moreover, independent testing has confirmed that Flowtac 2000 does not adversely affect the friction coeffient of the lubricant.
Another important attribute is the ease of handling. Lubricant manufacturers need to be able to produce quickly. The low viscosity and high efficiency of Flowtac 2000 enable manufacturers to fill and blend quickly to consistent high quality.
It is this combination of properties, together with our reliability and continuity of supply, that ensures our worldwide reputation for excellence.
Additionally, for incidental food contact applications in white oils, we can offer Contac 2000, with the same great performance. Moreover, for vegetable oil based lubricants and some esters, we offer Biotac.
WATER BASED INDUSTRIAL CLEANING
Maintenance engineers, industrial cleaners, and high pressure water cleaners frequently encounter flash rust corrosion as rinse water dries on recently cleaned equipment.
Industrial cleaning can mean large scale plant cleaning, commercial premises maintenance or cleaning of industrial equipment. Very often, industrial cleaners use water (or water/sand) at high pressure to clean plant equipment in industrial facilities. Automotive parts washing and impregnation and turbine cleaning are examples of industrial equipment cleaning.
In plant cleaning and parts washing / impregnation operations, operatives usually leave the rinse water on the surface to dry by evaporation. While the surface water dries it causes flash rusting on metal parts.
In aluminium parts washing and cleaning, water at elevated temperatures causes staining or bronzing corrosion during the rinsing. Many operatives observe this type of corrosion during parts washing and impregnation to prevent leakage from pores in cast aluminium parts.
FLASH RUST CORROSION INHIBITOR
Brad-Chem 563 is a multimetal corrosion inhibitor for use traffic film removers (TFR), industrial cleaning, flash rust, parts washing & impregnation, turbine cleaning, and textile washing, dyeing & bleaching applications.
Brad-Chem 563 is an excellent flash rust corrosion inhibitor. This corrosion inhibitor also gives great results for aluminium staining and bronzing. Increasingly, eco-blasters and other high pressure water cleaners use Brad-Chem 563 to prevent flash rusting for industrial cleaning.
Due to its versatility, low treat rate, and ready biodegradability, pressure testers also use Brad-Chem 563 for high pressure testing of tanks and pipework. Similarly, many other industries, including some highly specialised industries, are able to use Brad-Chem 563, due to these same properties. Certain types of deicing and winterization products use Brad-Chem 563 to prevent corrosion in use. Textile processing industries also use Brad-Chem 563 to protect metal components, such as zips and buttons.
For further information, see our knowledge base or contact us and speak to our technical team. Alternatively, telephone +44 (0)1942 261 0254 and ask for Technical.
CORROSION IN ACID RUST REMOVAL & CLEANING
Metal finishers, galvanisers, and manufacturers of pickling acid and acid based cleaners use acids for acid rust removal, and for removing metal oxides, and scale from metal surfaces. Acids react with insoluble rust and other metal oxides, which are bases, to form soluble salts that are removed with rinsing. However, acids also react with and dissolve the underlying metal surface. This causes further corrosion.
In order to control or reduce acid corrosion, manufacturers of metal pickling acids can add an acid corrosion inhibitor.
The ideal acid corrosion inhibitor should minimise corrosionby the acid without affecting its ability to remove dissolve the rust and scale. Furthermore, the ideal inhibitor should also have as low toxicity and as low environmental impact as possible.
Many acid CIs perform well in some acids, but have limited corrosion inhibitor efficiency in others; this presents challenges for the metal pickling & metal finishing industries.
Moreover, many commercially available acid corrosion inhibitors are harmful to human health or to the environment or both. Many acid cleaning product formulators and metal finishers use corrosion inhibitors that contain formaldehyde or produce formaldehyde in acids. Formaldehyde is the subject of increasing regulatory scrutiny worldwide, due to carcinogenic and skin sensitizing properties
ACID CORROSION INHIBITORS
Brad-Chem 593 is primarily used as a corrosion inhibitor in the following acids:
- Sulphuric acid
- Phosphoric acid
- Sulphamic acid
- Hydrochloric acid
- Citric acid
- Tartaric acid
It is a highly efficient multi-acid, multi-metal corrosion inhibitor for use in metal pickling, acid rust removal, and acid cleaning applications.
Brad-Chem 593 protects metal surfaces from acid corrosion without adversely affecting acid rust rust removal in acid cleaning, acid pickling and automotive wheel cleaners.
In addition to providing excellent corrosion inhibition efficiency, Brad-Chem 593 is low foaming. It als has low toxicity, low environmental hazard relative to many other products available elsewhere for these applications. Brad-Chem 593 and is an easy to handle, acid soluble, liquid product. Crucially, Brad-Chem 593 contains neither formaldehyde nor any components that form formaldehyde under acidic conditions.
BIOCIDAL PRODUCT REGULATIONS
Concerns over the use of biocide that either contains or generates formaldehyde in cutting fluids have led to new EU legislation. Metalworking fluids and coolants manufacturers will face new formulary challenges in 2018. The Biocidal Products Regulation will require authorisation of any commercially available biocidal products (BP).
Metalworking fluids and coolants manufacturers use biocides to reduce souring of water based coolants / soluble oils by micro organisms. Frequently, slide way oil mixes into the coolant, providing a source of sulphur nutrient for the microbes.
Many producers expect that the new legislation will restrict the use of certain types of BPs. Some BPs that they currently use will become unavailable. Moreover, many formulators expect that they will need to remove BPs that either contain or generate formaldehyde. They will need to replace with non-formaldehyde alternative products.
BIOCIDE STABLE CORROSION INHIBITORS
A soluble oil metalworking fluid typically contains a balanced mixture of water, dispersing agents, mineral oil, EP/Antiwear agents, corrosion inhibitors, metal deactivators and biocides. However, if a formulator changes one component, this change can alter the stability of other components in the fluid.
>Brad-Chem have developed corrosion inhibitors that have better stability in metalworking fluids formulated with non-formaldehyde biocides. Brad-Chem DP 3717 is a water soluble corrosion inhibitor for iron, steel, aluminium and ferrous metals with improved stability in metalworking fluids / coolants that are formulated with non-formaldehyde biocidal products.
The acid components that constituted the now discontinued product Corfree M1 form the basis of the new products. This new development means that manufacturers of metalworking fluids, soluble oils, and coolants can future-proof their metalworking fluids.
The new biocide stable Brad-Chem corrosion inhibitors not only replace both Corfree M1 and the bases that are typically used to neutralise it. Additionally, we can also work with customers to produce bespoke versions for specific applications if the annual volume is sufficient.

NEW BUILDING NEARING COMPLETION
Brad-Chem Ltd. will be relocating to purpose-built new premises at the end of 2017.
Brad-Chem is a chemical manufacturer based in Lancashire, United Kingdom. We manufacture corrosion inhibitors and speciality lubricant additive packages. Firstly, we market and sell our own manufacture products worldwide. Moreover, we are also the distributor for BRB International BV, Climax Molybdenum, and Nyco to our domestic markets.
The building of new premises is nearing completion and we will be moving in at the end of 2017. The move to the new purpose built facility is necessary due to growth in demand for our products. Similarly, our sales growth of the distributed product has also increased the need for greater capacity. Additionally, the move will increase our production and finished product storage capacity by fifty percent. Moreover, we will double the size of our R&D facility.
We supply worldwide, either directly, or through our network of distributors. In addition to our direct supply, Brad-Chem currently has distributors serving:
NEW PREMISES LOCATION
The new premises is located on the same industrial estate as our current premises. Following the move, our new address will be:
Brad-Chem Ltd., Unit D6, St Mary’s Court, Moss Industrial Estate, Leigh, Lancashire WN7 3PT. United Kingdom.
We intend to achieve the move to the new facility without disruption to supply or service. Moreover, our increased capacity will ensure even better average response and fulfilment times for spot enquiries and orders.
Additionally, the new site offers ongoing opportunities for further expansion. This extra capability is much needed as we continue to enter new market areas. In addition to new markets, our year-on-year sales growth also continues unabated in our existing focus market regions.
BRAD-CHEM LAUNCHES NEW SYNTHETIC BASE OIL RANGE
Brad-Chem Ltd is pleased to announce the launch of our expanded range of Polybutene (PIB) for the UK market. Additionally, we are expanding our range of Poly alpha olefins (PAO).
Brad-Chem will begin selling the new products to the UK and Ireland markets from the start of November
Lubricant blenders, rubber and plastics, and health and beauty care products manufacturers all use polyisobutylenes. Our polybutenes now range from low molecular weight lubricant base oils though to high molecular weight solid rubber.
The advantages of using polybutene as a base oil for lubricants or as a way to prevent rust for household ovens in storage are:
- Generally regarded as safe for incidental food contact
- Burns off cleanly with low carbon residue at temperatures above 270°C
- Highly shear stable
- Very good friction reduction
- Good compatibility with other base oil types
Due to their superb drying oil properties and adhesion, polybutenes are a vital component of caulks and sealants. Moreover, PIBs help minimize shrinkage on drying and improve pliability.
Similarly, hot melt pressure adhesives use these versatile additives for their plasticising and tack properties.
Polybutene also finds a number of uses as a plastics, rubber, and asphalt modifier. Film manufacturers add it to linear low density polyethylene (LLDPE) resin to improve the melt-flow, tear resistance, and cling properties of cling film. Compounders and plastics manufacturers also use it to improve the hot flow, flex, and impact strength of thermoplastics, such as polyethylene, polystyrene, EPDM, and EVA.
Polybutene is a long term stable extender and plasticiser for vulcanised rubber and can also add to the tack properties. Asphalt for road surfaces made with PIB has quick drying and good crack resistance.
POLY ALPHA OLEFINS (PAO)
Poly alpha olefin (PAO) base oils are incidental food contact approved Group IV synthetic base stocks with excellent lubricity and oxidation stability.
Long-life compressor oil made with PAO gives great cost / performance benefits over mineral or other synthetic base oil types.
Additionally, poly alpha olefins are an important component of semi- and fully-synthetic automotive engine oils.
For more detail on our ranges of polybutenes and poly alpha olefins, contact us.
WHAT ARE COPPER PASSIVATORS
Copper passivators inhibit corrosion of copper, brass, and yellow metals by rendering the metal surface less reactive. Due to their mechanism of action, they belong to the family of metal deactivators.
In general, copper passivators contain the azole functional group and a planar aromatic ring in their molecular structure. Most are solid at room temperature, with low water or oil solubility.
WHAT ARE THE ADVANTAGES OF LIQUID COPPER PASSIVATORS?
The advantages of liquid copper passivators are:
- Much easier to blend
- Better solution stability
- Optimised treat rates and performance
USES IN WATER OR WATER GLYCOL
Metalworking fluids manufacturers, heat transfer fluids manufacturers, and metal finishers use copper passivators to prevent copper and yellow metals corrosion. Many formulators experience difficulties with solid passivators, due to their low water solubility.
Brad-Chem have developed Brad-Chem 536 highly water soluble liquid triazole copper passivator. This product allows manufacturers to easily produce water soluble products that are effective and stable even at high concentrations. This product can be used in metalworking fluids, as a tank side post treatment, or in industrial cleaning and preventive maintenance applications.
While metalworking fluids and cleaning customers favour Brad-Chem 536, water treatment formulators use Brad-Chem 537 to protect copper, brass and yellow metals. Brad-Chem 537 is an excellent choice for water treatment for industrial cooling systems.
USES IN LUBRICATING OILS
Lubricating oil blenders generally use oil soluble corrosion inhibitors at much lower treat rates than those that are used in water based applications. Moreover, since lubricant manufacturers utilise a range of additive types, it is important to ensure that the corrosion inhibitors do not adversely compete with other additives.
We offer our unique range of speciality corrosion inhibitors for mineral oil and synthetic lubricants. Furthermore, we include multi-metal corrosion inhibitors as well as a liquid copper passivator and in our range for oil and synthetic lubricants. However, to ensure that additives do not adversely compete with each other in use, we also offer full additive packages.
We optimise the treat rates of all of the components in our full additive packages to ensure that they meet the relevant application specifications. Consequently, lubricant blenders are able to simply blend our easy-to-handle liquid additive packages into their base oils in order to produce finished lubricants with the correct EP/AW, antioxidant and anti-corrosion performances.
ACID INHIBITOR SUPPLY CHAIN CONTINUITY
Users of corrosion inhibitors for acids are increasingly experiencing supply chain continuity issues. Recently, a number of well-known acid inhibitor producers have withdrawn products from the market. Furthermore, some manufacturers are withdrawing products ahead of the 2018 deadline for European REACH registration.
Acid corrosion inhibitors help to prevent further corrosion when using acids to remove rust and scale from metal surfaces. For example, Brad-Tech 6037 is a corrosion inhibitor for acid metal pickling, used in the surface treatment and galvanising industries.
Other applications for these types of corrosion inhibitors include acid cleaners, wheel cleaners,water treatment, rust removers and descalers. While acids can clean metals by removing rust and scale, they can also cause damage by corrosion.
Many industry sectors use acids to clean metals. Moreover, surface treatments for structural metals use acids for surface pre-treatment. Supply chain continuity of acid inhibitors is, therefore, very important to industry. Consequently, the requirement for alternatives to the products being withdrawn from the market is imperative to maintain that supply chain continuity.
DIFFERENT ACIDS, DIFFERENT METALS
Different metals have different susceptibilities to corrosive agents. For example, Ferrous metals are relatively resilient in mild alkaline conditions, but more susceptible to acids and salts; whereas copper is sensitive to mild aminic alkalis.
Similarly, there is no “one size fits all” solution to the problem of acid corrosion. Some acid corrosion inhibitors work better in hydrochloric acid and others work better in other mineral or organic acids. Consequently, reformulating options are limited when the acid corrosion supply chain continuity is compromised.
To mitigate these problems, Brad-Chem Ltd. have developed a range of multi-metal corrosion inhibitors for the following acids:
We have optimized our range to give the best possible surface finish and the lowest weight loss. Furthermore, where possible, we have ensured that each of our products in this range give good inhibition in various acids and for various metals. As a result of this, customers are able to rationalise inventories.
For further information on our acid corrosion inhibitors, contact us
DIFFERENT TYPES OF BASE OIL
Lubricant blenders have traditionally used mineral oil as a base oil for machine lubricants. The first synthetic base oils became available in the late 1920s. Increased hydroprocessing also means that some mineral oils are either designated as synthetic oil or analogous to synthetic base oil. This news item will explore the properties and uses of different types of mineral oil and different types of synthetic oil. Additionally, It will also explore differences of properties of base oils within these categories.
The American Petroleum Institute (API) categorises lubricant base oil into five groups:
- Group I – solvent refined mineral oil
- Group II – hydrotreated mineral oil
- Group III – severely hydrocracked mineral oil
- Group IV – Poly alpha olefin(PAO)
- Group V – All other base oils not included in groups I-IV
Worldwide, the majority of lubricant manufacturers primarily use Group I base oil. Industry analysts expect this Group I dominance to continue until 2020. Many producers and formulators consider that Group III is more like a synthetic oil, despite being produced from mineral oil feed stock.
Lubricant blenders use mostly mineral base oils for high volume and price sensitive applications, due to the low cost, widespread availability, and ease of use. Speciality blenders use synthetic base oil for specialized higher value applications.
MINERAL BASE OILS
Demand for mineral base oils far exceeds that for synthetic oil. The table shows a summary of some of the most common advantages and disadvantages of the API groups of base oils. However, one should note that, even within groups, individual base oils can sometimes exhibit different performances than others in the group. This is particularly true for group V, which is an amalgam of various synthetic base oil types.
Group I and Group II mineral oils have traditionally been used for the higher volume applications, such as engine oils and and for some of larger volume industrial lubrication uses. The development of more modern cars and more stringent specifications means that higher performance base oils are now needed for the higher specs.
Many higher tier synthetic engine oil formulations use Group III base oils and their use for specialist industrial lubricants is also increasing. Changing from Group I or Group II to Group III can be fraught with difficulty. The differences in characteristics behaviour between Group I and II are much less significant than the differences between group III and the other two mineral oil groups. Moreover, Group III oils are closer in structure and behaviour to Group IV synthetic oils than to other mineral oils. In particular, the lower additive solubility and reduced additive response can cause problems for formulators in changing over from other mineral oil API groups.
GROUP IV SYNTHETIC BASE OILS
Group IV consist of poly alpha olefin (PAO) synthetic base oil types. PAOs do not contain the natural inhibitors and antioxidants that are present as impurities in Group I and Group II mineral oil. They also have lower additive solubility and additive response. This means that they require a greater treat rate of additive. However, when fully additized, the lubricant performance is often significantly better than that which blenders can achieve using mineral oils.
GROUP V SYNTHETIC BASE OILS
Group V consists of any base oil that does not fit into the other four groups. Synthetic Esters, poly iso-butylenes (PIB) alkyl benzenes and poly alkylene glycols (PAG) are group V synthetic base oils. Although a mineral oil type, API also consider naphthenic oil to be group V. Moreover, with the exception of having low impurity levels and good additive solubility, naphthenic oils share few of the other typical characteristics of this group.
Synthetic ester base oils are condensation reaction products of a fatty acid plus an alcohol, diol, or polyol. Furthermore, the chemical structures of the acid and alcohol raw materials determine the properties of the base oil. Consequently, speciality ester manufacturers can engineer the properties of the base oil to meet the precise requirements of certain application types. Typically, end users use ester based lubricants for high temperature, 2-stroke oil, and marine lubricant applications. Many formulators use synthetic esters for eco-friendly lubricants and lubricants for incidental food contact applications.
Poly iso-butenes (PIB) are very versatile and can act as synthetic base oils or as additives. Typical characteristics include excellent high temperature properties, excellent drying oil characteristics, plasticising properties, excellent adhesion, and excellent lubricity. For these reasons, manufacturers of lubricants, greases, food grade lubricant, forming lubricants, sealants, cling film, and hot melt adhesives all use PIB. Higher molecular weight grades are rubbery solids. Polymer formulators add these grades to thermoplastics, elastomers, or rubbers to make to cling film wraps or make hot melt adhesives. The PIB component adds tackiness and flexibility to these products.
Some very specialised applications use polyalkylene glycols (PAG). Tradtionally, there has been a limited market for PAG lubricants. However, this market has started to grow in recent years. Typically, PAGs have good inherent lubricity, good environmental profiles, and they are non-combustible. However, they aslo have somewhat unpredictable additive solubilities. PAG can also be used for incidental food grade lubricant and grease applications.

AEROSPACE PRODUCTS FOR CORROSION & LUBRICATION
Manufacturers of runway deicers, wing deicers, aerospace cleaners and dry film lubricants face very specific challenges. Typically aircraft and payloads makers use strong, yet lightweight materials, such as advanced light aluminium alloys. Operators must prevent the possibility of in-flight failure of any of the aircraft parts. Moreover, many conventional lubricants can evaporate or cease to function in a thin atmosphere or in the vacuum space.
In order to maintain flight schedules all year round, many airports use deicer to clear runways in the winter. Additionally, many flight operators use aircraft and wing deicer to enable their planes to take off. Since these products go to ground in the melt water, it is important to use safe, biodegradable, non-bioaccumulating products.
In general, the transport industry generates and releases a lot of atmospheric carbon. Governments and the industry take very seriously the responsibility to mitigate the environmental impact of air travel. Furthermore, aircraft developers are making great improvements in fuel efficiency and alternative energy powered flight. Airports and flight operators are making advancements in reducing carbon emssions.
AEROSPACE PRODUCTS CAN REDUCE CARBON EMISSIONS
Improved lubricants can make an important contribution to carbon emissions reduction. Specifically, improved lubrication can reduce fuel consumption.
Moreover, lower oxygen demand biodegradable cleaners and deicers also help reduce the carbon footprint. Oxygen demand is a measure of the effort and energy an organism has to put into biodegrading a substrate chemical.
In biodegradation, organisms use organic matter for nutrition. Nutrition involves absorption of nutrients, breaking them down by digestion, and repurposing their constituents. If the nutrient substrate chemical isn’t a protein or a fat, the products of digestion are used for respiration.
All nutrition processes require an initial input of energy, this energy being provided by respiration. The more energy that is needed to absorb and digest a substrate, the more the organism must respire to release the required energy. In aerobic respiration, the organism reacts oxygen from the air with the breakdown chemical products from digestion. This reaction releases energy and the waste products are carbon dioxide and water.
If a biodegradable chemical has a low oxygen demand, it means that organisms can digest it easily. Consequently, an organism will not need to respire as much when degrading a lower oxygen demand material. Furthermore, this means that organism will use less oxygen and will release less carbon dioxide to the atmosphere. Carbon dioxide is the same greenhouse gas that burning aviation fuel releases to the air. Therefore, using lower oxygen demand aerospace deicers and cleaners, significantly reduce carbon emissions.
AEROSPACE LUBRICANT APPROVALS
In thin atmospheres or in the vacuum of space, many lubricants become ineffective. For example, oil and other liquid lubricants can evaporate away at low air pressure. Consequently, liquids can only be used as aerospace lubricants in closed systems.
Graphite is a solid lubricant made of graphene layers that can slide over each other. However, graphite needs to have some adsorbed water molecules between its layers in order for them to slide. At low air pressure, the water desorbs and evaporates away, leaving a non-lubricating graphite film.
By contrast, molybdenum disulphide is an intrinsic solid lubricant. Layers of molybdenum disulphide are further apart and can slide without the need for adsorbed water. Molybdenum disulphide can be applied as a dry film lubricant using one of our dispersions.
AEROSPACE DEICERS AND CLEANERS APPROVALS
The metals and alloys used in aerospace engineering can corrode when in contact with water. This can take the form of melt water from deicing, or it can come from an aqueous cleaning product.
Aircraft manufacturers use many different specialised metals and alloys. Any maintenance fluid product that contacts these metals must pass international standards for corrosion. Testing houses, such as SMI typically run a battery of standardised corrosion tests on aerospace products before granting approvals.
Brad-Chem helps many manufacturers of aerospace deicers and cleaners to gain aerospace approvals. We work with the manufacturers to ensure that we offer aerospace corrosion inhibitors that give optimal results in their formulations. Additionally, aerospace metals and alloys suppliers also use our aerospace products.
Different deicer and cleaner manufacturers face different corrosion challenges. Each manufacturer has their own formulation and they affect different metals. Consequently, we help to ensure that we offer the best possible solution for each formulation.
Contact us to see how we can help your product to gain aerospace approvals.
HOW THE MARKET IS CHANGING
Acid corrosion inhibitors are becoming harder to source. Regulatory and price pressures are increasing. These factors reduce the availability and increase the price of acid corrosion inhibitors. Manufacturers of inhibited acid, metal finishers, and water treatment companies use acid corrosion inhibitors to reduce corrosion during rust removal.
Several acid inhibitors manufacturers have discontinued some of their products. Availability of many others is generally low. Additionally, a number of manufacturers have significantly increased prices recently. Moreover, price increases may be due to reduced supply options and stricter regulation of chemical raw materials.
The changing market conditions have not affected the prices of Brad-Tech 6030 and Brad-Chem 593 acid inhibitors in this way. Brad-Chem 593 gives highly efficient inhibition in many different acid systems. Brad-Tech 6030 is a unique, cost-effective acid corrosion inhibitor, primarily for hydrochloric acid, and acetic acid. Moreover, this versatile inhibitor is also effective in neutral to mildly alkaline conditions.
USES OF ACID CORROSION INHIBITORS
Many industries use acids to remove rust, scale and dirt from metals. The acids chemically react with metal oxides in an acid-base neutralisation. The reaction products are generally water soluble and they dissolve in the acid. Accordingly, industries often use this process to clean metals prior to onward processing or metal finishing. For example, many galvanisers use acid metal pickling to remove rust and scale prior to galvanising.
Some applications require the acid to clean the metal, leaving a shiny surface. However, for other applications a slightly duller surface finish will suffice. Furthermore, coatings industries often prefer a duller surface that gives the coating a key. By contrast, most cleaning industry applications necessitate a shiny finish.
COST-EFFECTIVE ACID CORROSION INHIBITORS
Increased cost and reduced availability of acid corrosion inhibitors affect industries that rely on acid cleaning and rust removal. Brad-Chem manufacture a cost-effective range of acid inhibitors with excellent supply continuity.
Our acid corrosion inhibitors give multi-metal protection and, therefore, they protect various metals and alloys. Acid cleaning formulations containing Brad-Tech 6030 and Brad-Chem 593 have gained approvals in many industry sectors.

R & D AND TECHNICAL SUPPORT
Chemical laboratory researchers, and lubricant and cleaning product developers test
generally follow similar work flows. Firstly, they identify a market need and then they determine a solution. If they don’t know if an existing product would answer the new requirement, they devise laboratory tests to find out. Moreover, if no solution is currently available, they determine if it is feasible to develop a new product to solve the new need.
Developing a new speciality lubricant, metalworking fluid, brake fluid, or cleaning chemical also follows a set pattern. First, the developers identify candidate ingredients through either knowledge of prior art or screening test results. Secondly, they combine promising ingredients into several judiciously predetermined candidate formulations. They then devise and carry out a full testing program to identify the best performing formulations. Based on the results of this testing, they then either attempt to refine the formulations and retest, or release the new product.
Due to limited resources or a lack of available guidelines on some types of test, lab chemists sometimes have to outsource some tests. External testing houses can test products against published international standards. Furthermore, they can often help with chemical identification and more academic research. However, for non-standardized tests that mimic real world conditions, it is sometimes better to develop and use proprietary test methods.
Here at Brad-Chem, we have many years of technical development experience across various industry sectors. We have developed our own test methods that can be developed to match the conditions in which your products are used. We can test our additives in your products in order to help find the best solution for your product development.

CONTINUITY OF SUPPLY & QUALITY
Successful lubricant blenders and Industrial cleaning companies need excellent continuity of supply of raw materials. Moreover, suppliers who can demonstrate great quality, reliability, and ability to supply at all times can form great long-standing customer relationships.
Quality is imperative in any trustworthy supply chain. Furthermore, it doesn’t stop at ensuring product quality. The best suppliers ensure the highest quality is extended through all of their processes from receipt of an enquiry through to after care.
Purchasers evaluate suppliers using several factors, including price, product specification, quality, and continuity of supply. Additionally, they have different selection criteria for suppliers of speciality and commodity materials. For instance, if many suppliers are offering the same specification of high volume commodity raw material, price and availability are paramount. By contrast, there are fewer suppliers for any given speciality and, therefore, quality and continuity of supply are primary motivations.
Consequently, while purchasers will often change suppliers for commodities, they prefer to retain the same suppliers for speciality additives. In order to do so, they must find a supplier upon whom they can rely. A speciality additives supplier who can maintain consistent supply of consistent quality material on the agreed dates is most valuable.
CONSISTENT QUALITY THROUGHOUT, ALWAYS
Brad-Chem prioritizes the utmost high quality throughout our operations. This encompasses:
- Technical and commercial support with enquiries
- Order processing

SYNTHETIC LUBRICANTS VS. MINERAL OIL
Lubrication Engineers use Synthetic lubricants for applications that require a higher level of performance than can be achieved with Group I or Group II mineral oil. For example, where a mineral oil based compressor oil may give 1000 – 4000 hours performance, a PAO/Ester based oil may give >8000 hours. Moreover, some ester based compressor formulations now give >10,000 hour performance.
Industrial and automotive users select lubricants on the basis of price and performance. If a specific application requires a lubricant that performs better than mineral oil then the user will select synthetic oil. However, in applications that would not benefit significantly from the improved performance, users select mineral oil, due to lower cost. The majority of applications are currently served by mineral oil based lubricants.
Globally, lubricant blenders produce much larger volumes of mineral oil based lubricant than synthetic. Correspondingly, the market generally characterizes mineral oil based as commodity / semi commodity, and synthetic lubes as specialities.
Formulators can use some of the same additives for manufacturing synthetic lubricants as those used for mineral oil. However, many blenders find that not all of the additives that are suitable for mineral oil are necessarily suitable for some synthetic types. Additionally, blenders generally use a higher additive treat rate when making synthetics due to the lower additive response of synthetic base oils
Mineral oil based applications constitute the largest market share. Correspondingly, most lubricant blenders set up their plant equipment primarily for manufacturing mineral oil based lubricants. Consequently, some manufacturers do not have any synthetic lubricant blending facilities at all.
WHY DEVELOP A SYNTHETICS OFFERING?
End users can generally use mineral oil based lubricants for most applications, and this is the biggest market. Price considerations tend to drive the market for mineral oil based lubricant. By contrast, users of synthetic lubricants generally prioritise performance. Many industrial customers use both types for different applications. Similarly, blenders can add a range of speciality synthetics to their offering to help to offset cyclical trends in the global economy.
Often, suppliers who can offer a diversified portfolio of mineral oil and synthetic lubricants can provide a one-stop shop. Furthermore, such suppliers can open up new opportunities outside of their traditional customer base.
Applications that favour synthetic lubricants over mineral oil include:
- Speciality industrial compressor lubrication
- Fire resistant and top tier hydraulic oil
- High temperature chain oil
- Incidental food contact
- Clean burn-off applications
- Refrigerator compressor lubricants
- Environmentally sensitive total loss applications
- EU Ecolabel Lubricants and Marine EAL
- Offshore and subsea
- High performance automotive
Brad-Chem manufacture speciality lubricant additive packages. We formulate liquid additive packages that mix easily into synthetic base oils to make synthetic lubricants for a range of applications. We offer packages for use in synthetic esters, natural esters, polyisobutylenes (PIBs),poly alpha-olefins (PAOs), and polyalkylene glycols (PAGs).
Brad-Chem also distribute a large range of top quality synthetic base oils to the UK market. We offer Nyco Esters, as well as an extensive range of polyisobutylenes (PIBs) and PAOs. Developing your new range of synthetic lubricants could not be easier; simply mix the additive package and base oil together and stir. Moreover, for some speciality applications we can even do the mixing for you and you can simply rebrand.
See our product ranges for details of our lubricant additives and synthetic base oils.
METAL DEACTIVATORS AND RUST INHIBITORS
Metal deactivators prevent corrosion by passivating metal surfaces. Passivation leaves a less chemically reactive layer on the metal surface. Correspondingly, metal deactivators render the metal surface less susceptible to corrosion. Corrosion inhibitors prevent corrosion reactions from taking place; but, do not necessarily chemically alter the metal surface.
Industrial and automotive lubricant blenders blend additives into a base oil in order to manufacture finished lubricants. The lubricant formulators use a mix of additives. Specifically, most lubricant blenders use the following components to make a finished lubricant:
- Base oils
- Extreme pressure (EP) additives
- Anti-wear (AW) additives
- Corrosion inhibitors
- Metal deactivators
Additionally, for some applications, they also use viscosity index improvers, oil tackifiers, pour point depressants, light stabilisers, solid lubricant dispersions, anti foams, detergents, and dispersants.
Antioxidants carry out their functions in solution in the oil. By contrast, EP/AW additives, corrosion inhibitors, and metal deactivators operate at the surfaces of the moving parts. Furthermore, these four additive types compete with each other for access to surface sites. It is, therefore, important for formulators to carefully balance the mix of additives that they use to mitigate competition.
Blenders add metal deactivators to lubricants, primarily to protect copper and yellow metals. The deactivators passivate the surfaces of copper, bronze, or brass pipework and fittings. Conversely, they add corrosion inhibitors to protect iron, steel, magnesium, and aluminium. Corrosion inhibitors protect these more reactive metals whose surfaces can not sufficiently passivate.
MULTIFUNCTIONAL LUBRICANT ADDITIVES
Some additives perform or assist with more than one function. For example, the anti-wear agent ZDDP also acts as an antioxidant. Since, lubricant blenders can use ZDDP either as an antioxidant, or as an AW agent, or for both, we consider it to be multifunctional. Conversely, some other additives perform only a single function.
Clearly, if blenders use an additive for only one function then that additive is not multifunctional. However, some additives perform one function and, indirectly, assist with another. Specifically, such additives perform their function, while also augmenting the protection that a different additive offers. For example, a metal deactivator may also help to improve the thermo-oxidative stability of a lubricant by impeding the formation of oxidation catalysts.
MULTIFUNCTIONAL METAL DEACTIVATOR & CORROSION INHIBITOR
We have developed Brad-Chem 526, which is a corrosion inhibitor and metal deactivator for lubricant oil. This product not only offers excellent copper & yellow metals protection; but, also, protects iron, steel, aluminium and magnesium. Moreover, in some applications, some users of Brad-Chem 526 have also reported seeing better lubrication and oxidation stability.
Brad-Chem 526 mixes readily with mineral oil and synthetic base oils. Blenders can use Brad-Chem 526 for making engine and gear oils, as well as hydraulic oils and many industrial applications. Additionally, this product performs highly effectively, even at low treat rates; thus, reducing the competition with other surface additives.
Contact us for further information or technical support.
AUTOMOTIVE FLUIDS MANUFACTURING CHALLENGES
Automotive fluids perform vital functions in maintaining the engine, power transmission, brakes, screen wash, and air conditioning. Automotive aftermarket fluid manufacturers blend additives into base fluids. The blenders select the base fluids and additives according to the primary function of the fluid and the requirements of the system. For example, they would select an ATF additive package and a suitable base oil in order to blend an automatic transmission fluid.
Maintenance mechanics select the aftermarket automotive fluids according to the make of vehicle. In general, vehicle manufacturers create specifications for the performance levels that fluids for their systems must meet.
Often, vehicle manufacturers also specify tight limits of physical properties that many experts would consider unlikely to affect performance. Additionally, many manufacturers do not make details of their specification requirements easily available for openness and transparency. Some vehicle manufacturers state that consumers must only use their brand of fluids. Others state that consumers must only use fluids that they approve. Frequently, they list approved fluids by trade name without quoting any performance test results or approval criteria.
Aftermarket product producers increase consumer choice, allowing consumers to decide. Blenders select additives that protect both the base fluid and the mechanical parts of the system into which it is filled. For example, brake fluids must meet international standards for corrosion, starting and final pH, density, water content and materials compatibility. Additionally, formulators must ensure that the fluid is within the viscosity limits and exceeds the minimum boiling points of specific applications.
OVERCOMING THE CHALLENGES
Brad-Chem Ltd. manufactures antifreeze/engine coolant super concentrates, and a brake fluid corrosion inhibitor package. Additionally, many automotive engine and gear oil manufacturers use Brad-Chem 526 as their corrosion inhibitor package.

HYDROCHLORIC ACID INHIBITOR USES
Metal finishing, galvanising, and metal cleaning industries use inhibited hydrochloric acid to remove rust and scale from metals. Iron and steel react with oxygen and moisture in the air, forming insoluble basic (alkaline pH) iron oxides (rust) on the surface. Hydrochloric acid reacts with these solid, insoluble iron oxides, turning them into soluble iron chlorides that wash off. However, the acid also reacts the underlying metal surface and causes corrosion. Consequently, steel producers add a hydrochloric acid corrosion inhibitor to mitigate the corrosion reaction, without impeding the rust removal reaction.
Some users use inhibited acid to reclaim and reuse rusted used parts. Others use it to produce a clean, rust-free metal surface that they can then process further. For example, galvanisers and powder coaters remove the rust from structural steel before applying an anticorrosion coating.
Acid cleaners and picklers who use hydrochloric acid to remove rust and other unwanted surface contamination use hydrochloric inhibitors to improve the surface finish. Moreover, many finishers and coaters find that they experience fewer quality issues when using a hydrochloric acid inhibitor in their surface preparation.
RECENT ISSUES IN ACID INHIBTOR SUPPLY
Many users in the industry report that they can no longer obtain the flagship product from a major European acid corrosion inhibitors manufacturer. Moreover, many suppliers have had to increase their prices significantly, due to increased costs.
Additionally, greater chemical regulatory pressures are impacting on the costs and availability of acid corrosion inhibitors. Despite moves towards a Globally harmonised system, chemical regulatory regimes remain divergent. Consequently, chemicals that are available in one part of the world may, in some cases, not be permissible in others. Multinational industries that use inhibited acid may find that their regular hydrochloric acid inhibitor is no longer available in some of their territories.
NEW HYDROCHLORIC ACID INHIBITOR
Brad-Chem have developed Brad-Chem 592. Brad-Chem 592 is a hydrochloric acid corrosion inhibitor with excellent performance and regulatory compliance profile.
Our technical team have tested this product extensively against commonly used competitor products in concentrated and dilute hydrochloric acid. Brad-Chem 592 gave inhibitor efficiency results closely comparable to those of a well-known market leading product, which is now difficult to obtain in the EU. We have tested the MDD weight loss corrosion inhibitor efficiencies and surface finish on the most commercially important mild and stainless steel types. Excellent results were obtained in all cases.
We have formulated Brad-Chem 592 using the newest chemical technologies available and it is designed with improved toxicological profile in mind. This product does not release formaldehyde, is non-flammable, and does not carry a toxic classification by inhalation or skin contact. Moreover, we expect that this new corrosion inhibitor will be acceptable in most regulatory regimes.
Some acid corrosion inhibitor manufacturers have experienced cost increases and the prices of several competitor products have significantly increased. Concurrently, some industry users are finding competitor products more difficult to source, due to lower availability. We offer Brad-Chem 592 as a cost effective alternative with good continuity of supply.
Contact us for further details.
IMPORTANCE OF ENSURING SUPPLY CONTINUITY
Ensuring supply continuity of corrosion inhibitors is crucial for industrial cleaning, aerospace cleaning and car care fluid manufacturing. Moreover, such maintenance industries play a critical role in maintaining machine efficiency, reducing fuel demand, and failure prevention. Consequently, manufacturers must maintain a secure supply chain for the benefit of the wider economy.
In 2017, a study concluded that machine downtime costs British manufacturers more than £180bn per year. Many factors impact downtime, including corrosion, which affects both machines operating in corrosive environments, and lubricated parts. Corrosion inhibitors reduce machine corrosion issues and help to avoid costly downtime.
US airlines have estimated that the average fuel use reduction due to regular engine washing is 28 gallons (127 litres of fuel) per flight. Turbine cleaners use corrosion inhibitors to prevent flash corrosion and aluminium staining reactions in their cleaning operations.
Car care fluids include automotive antifreeze, brake & clutch fluids, cleaning products and fuel additives. Furthermore, car owners and fleet owners use these products to ensure continued safe and reliable operation. Suppliers of additives such as corrosion inhibitors for these products, therefore, create benefits for the wider economy, by ensuring supply continuity.
CHALLENGES TO ENSURING SUPPLY CONTINUITY
Businesses generally face geopolitical, environmental, sociocultural, and economic threats to maintaining continuity. As a UK manufacturer, we currently face geopolitical uncertainties due to BREXIT. The United Kingdom will establish trading relationships with Europe, and the rest of the world. We must ensure that we counteract or minimise any adverse effects of future trading terms and regulatory frameworks on our raw material imports.
Due to the sustained period of historically low interest rates, many businesses worldwide now hold greater than historical average nett debts. Moreover, some economic commentators worry that threats to the supply side will push some businesses to default on some of that debt. Should such defaults impact our customers, we must monitor cash flow carefully in the coming months and take advice from our credit insurers. Additionally, we maintain close relationships with sustainable raw materials suppliers, and we work with sustainable overseas distributors.
Like many other manufacturers, we are assessing and monitoring the risks to the supply chain from Coronavirus COVID 19. Some producers of raw materials in countries of high incidence may experience periods of shutdown. Correspondingly, we must ensure continuity of our raw material supplies.
At Brad-Chem, we ensure that we source our raw materials from at least dual approved sources. We have assessed our supply chain security in relation to Coronavirus Covid 19. We have identified several key raw materials either immediately or ultimately originating in China.
Due to BREXIT, we have already increased our stock holding by 50%. In anticipation of any supply chain issues that may arise from Covid 19, we are further increasing our stock holding for the raw materials that we believe may be affected.
We believe, therefore, that we are well-positioned in ensuring supply continuity in any foreseeable event of disruptions arising from Covid 19 or BREXIT.
If you seek reassurances about the continuity of products that we supply to you, please Contact us for further details.
COVID-19 MINIMIZING THE RISKS
The COVID-19 global pandemic carries the individual cases risk of human-to-human transmission. Additionally, we face the collective risk of overburdening healthcare provision capacity if infection transmission rates increase significantly.
We know that COVID-19 spreads by respiratory droplets, and by contact with contaminated surfaces. The known or suspected routes of infection are:
- Inhalation (nose, mouth)
- Ingestion (mouth)
- Entry at other mucous membranes (e.g. eyes)
- Contaminated surfaces, hand to face transmission
- Entry through cuts and broken skin
We have implemented protocols that reduce the possibilities of exposure and transmission.
COVID-19 SAFETY POLICY
In response to the COVID-19 risks and to ensure the safety of our staff, customers, and drivers, we have implemented the following:
- No visitor policy
- WHO recommendations for best hygiene practices across our site
- Maintain social distancing minimum 2m between personnel on site
- Maintain at least 2m distance from drivers during loading and unloading of trucks
We remain open for business and we will continue to supply in accordance with your requirements.
We are proud to play our part in supporting the cleaning, cooling/heat transfer, and speciality lubricants industries’ response to the current healthcare challenges.
