CARC Coating for Acid and Alkali Resistance

Q. What will CARC paint protect against? Will it protect aluminum frames from acids and alkali? Looking for a paint that can protect aluminum from acids. Is there such a paint or coating?

A. CARC is not intended for the purposes you mention. Before I go off into the blue yonder with a suggestion I really should know more about the aluminum frames. The more you can tell me, the better I will be able to give you some suggestions.

Q2. Looking at putting a coating on a remote control robot for Hazmat. The robots have an aluminum frame. They are on the Remotec website at www.remotec-andros.com. Your input would be greatly appreciated.

A2. CARC is intended for military use where the aluminum has the potential to be exposed to chemical warfare conditions. Moreover, CARC is a camouflage coating. If you do not need either camouflage capabilities or if the aluminum frames are not expected to come into contact with chemical warfare agents, you can go with a conventional industrial epoxy primer followed by one or more coats of a two-component polyurethane. Of course, do not forget the need for excellent surface prep of the aluminum.

I hope this helps.

Best wishes,

Ron Joseph
