Coating other than lacquering copper and brass rolled products
Q. Copper and Brass are prone to Oxidation due to condensation of the entrapped moisture between the layers of a rolled products. Can anyone suggest me any coating for copper and brass rolled products?

A. Hi Sachin. Things you might want to investigate include sodium benzotriazole ⇦ on eBay or Amazon [affil links] and variants, and chromate conversion coating. Good luck.

Q. Sir,
We are currently using benzotriazole but can you suggest any superior metal protection?

A. And if I compose a second response, Sachin, will those efforts likewise be dismissed with another "we already tried that"? :-(
Let's do it the other way: tell us what you've tried and in what ways those attempts were unsatisfactory. What seemed to be the most promising thing you tried? Thanks.

Q. I am an engineer in a company manufacturing copper and brass rolled products, addition of arsenic during melting stage gives a good resistance to Oxidation, but the setup requires a large investment. Can I get a solution to solve the oxidation once the rolled product is ready and the resistance to the same last for a longer duration.
