BTA 1H-Benzotriazole 95-14-7

1H benzotriazole/1,2,3-benzotriazole (BTA) CAS 95-14-7 appears as white to slightly yellow flakes, granules, or needles; This product is mainly used as a rust inhibitor and corrosion inhibitor for metals such as silver, copper, lead, nickel, zinc, etc. It is widely used in rust proof oil (grease) products and is mainly used as a gas-phase corrosion inhibitor for copper and copper alloys, circulating water treatment agent, automotive antifreeze, photographic anti fog agent, polymer stabilizer, plant growth regulator, lubricant additive, UV absorber, etc. This product can also be used in combination with various scale inhibitors, bactericidal and algicidal agents, especially for the corrosion inhibition effect of closed circulating cooling water systems.1,2,3-benzotriazole forms covalent and coordination bonds with copper atoms, often replacing each other to form chain like polymers. A multi-layer protective film is formed on the surface of copper to prevent redox reactions and provide corrosion protection. The same effect is also applied to metal materials such as lead, cast iron, nickel, and zinc.
