Benzotriazole CAS 95-14-7 Use
Metal rust prevention and corrosion inhibition
Copper and copper alloy protection: Forms covalent bonds and coordination bonds with the metal surface, generating a chain-like polymer protective film to prevent oxidation and corrosion.
Multi-metal applicability: It has corrosion inhibition effects on metals such as silver, lead, nickel and zinc.
Industrial water treatment
Circulating water system: It is used in a closed-loop circulating cooling water system to prevent copper pipe corrosion.
In combination with scale inhibitors: When used in conjunction with bactericides, algaecides and scale inhibitors, the corrosion inhibition effect is enhanced.
Automobile industry
Antifreeze additive: Added to ethylene glycol-based antifreeze to prevent corrosion of metal parts.
Other industrial applications
Lubricating oil and grease: As an extreme pressure additive, it is used in industrial gear oil and anti-wear hydraulic oil, providing rust prevention and vapor phase corrosion inhibition functions.
Photographic anti-fogging agent: Prevents film and photo paper from oxidizing and fogging.
Polymer stabilizer: Used in plastics and rubber to inhibit fading caused by ultraviolet rays.
Electroplating additives: Prevent metal discoloration during copper plating, silver plating and zinc plating processes.
