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 Recently, a number of well-known acid inhibitor producers have withdrawn products from the market.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 Consequently, the requirement for alternatives to the products being withdrawn from the market is imperative to maintain that supply chain continuity.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.
