1 2 3-Benzotriazole, BTA Chemical


Benzotriazole is bitter and odorless. Its boiling point is 204℃ (15mmHg). 1 2 3-Benzotriazole is soluble in alcohol, benzene, toluene, chloroform, and dimethylformamide. And the benzotriazole corrosion inhibitor is slightly soluble in water.

BTA chemical is mainly used as rust-preventer, anti-freezing liquid, antioxidant additive (including lubricating oil, hydraulic oil, brake oil, transformer’s oil), emulgent, water stabilizer.

Also, benzotriazole (BTA) is used as 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.
