a. Anti-rust grease: BTA(benzotriazole) can be used in anti-rust grease products, which has a particularly obvious anti-corrosion effect on copper and its alloys, silver and its alloys, and is mostly used as a vapor phase corrosion inhibitor for copper and copper alloys.

b. Water treatment reagent: BTA(benzotriazole) can be used in circulating water treatment reagent to play a role in corrosion inhibition.

c. Automotive antifreeze: BTA(benzotriazole) can be used in automotive antifreeze to play a role in corrosion inhibition and sterilization.

d. Photographing industry: BTA(benzotriazole) can be used in photographing industry to play a role in anti-fog.

e. Rubber and plastics industry: BTA(benzotriazole) can be used in macromolecule stabilizer to restrain color fading.

f. Agricultural pharmaceutics: BTA(benzotriazole) can be used in plant growth conditioning agents.

g. Electroplating industry: BTA(benzotriazole) can be used as a chromium fog inhibitor in the chromium plating industry to prevent the generating and harm of chromium fog, which can increase the brightness of the plating.

h. Scale inhibitor: BTA(benzotriazole) can be used in various scale inhibitors, to be used together with bactericide and algaecide.

i. Coating and oil paint: BTA(benzotriazole) is also an excellent UV absorber, with an absorption wavelength of 290-390 nanometers, it also can be used as an outdoor coating additive, significantly reduce the fading of color(coating) caused by ultraviolet damage.
