Introduction
FUNTAG CU250 is a water-soluble benzotriazole derivative. It has excellent anti-corrosion properties for copper, and also improves the rust resistance of ferrous metals.
FUNTAG CU250 has extremely low foam, good stability of hard water, soft film residue after volatilizing, which makes it easy to clean.
FUNTAG CU250 can effectively inhibit the precipitation of cobalt.
