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.
