1,2,3 Benzotriazole (BTA)

BTA is one of the most effective corrosion inhibitors for copper and copper alloy used in various industries. Further positive effects can be seen in protection of steel, grey iron, Cadmium and Nickel.

 Applications:

cooling water systems / industrial water treatment

industrial lubricants (e.g. drilling and cutting fluids)

dishwashing tablets (silver protection)

metal detergents and polishing

coolants

VCI papers / metal packaging

antifogging agent (photo)

Usage:

BTA is bitter, odorless, boiling point is 204℃ (15mmHg),soluble in alcohol, benzene、toluene、chloroform and dimethylformamide, and slightly soluble in water. It's mainly used as rust-preventer, antifreezing liquid, antioxidant additive(including lubricating oil, hydraulic oil, brake oil, transformer's oil), emugent, water stabilizer, the additive for high molecular materials (polyester and polyesteramide) capacity of ultraviolet resistance and anti-static electricity, photographic antifogging agent, copper mine flotation, metal's slow corrosion etc.
