1,2,3-Benzotriazole
1,2,3-Benzotriazole BTA mainly used as antirust agent and corrosion inhibitor for metals. It is widely used in the antirust oil products such as gas phase corrosion inhibitor, in treating agent for recycling water ,in antifreeze for cars antifogging for photograph, also used as stabilizer for macromolecular compound growth regulator for plant, lubricant additive, ultraviolet absorbent etc. It can be used together with many kind of scale inhibitors and bactericide and algaecide, show excellent anticorrosion effect in close recycling cooling water system..Description of goods: 1,2,3-Benzotriazole

Properties:
BTA is white to light yellow needles, m.p. 98.5 deg.] C, boiling point 204 ℃ (15 mm Hg), slightly soluble in water, soluble in alcohol, benzene, toluene, chloroform and other organic solvents.
BTA copper corrosion inhibitor can be adsorbed on the metal surface to form a thin film to protect copper and other metals from corrosion and atmospheric harmful media.
BTA can be absorbed on metal surface and form a thin film to protect copper and other metals.
Application
1.Benzotriazole is used in anti-rust oil (fat) products. It has obvious
anti-corrosion effect on copper and its alloys, silver and its alloys. It is
mostly used as a vapor phase corrosion inhibitor for copper and copper alloys.
, car antifreeze, photographic antifogging agent, polymer stabilizer, plant
growth regulator, lubricant additives.
2.Benzotriazole can also be used as a chromium smog preparation in the chrome
plating industry to prevent the occurrence and harm of chromium fog. Increase
the brightness of the plated parts.
3.Benzotriazole can also be used in combination with various scale inhibitors
and bactericidal algaecides.
4.Benzotriazole is also an excellent UV absorber with an absorption wavelength of 290-390 nm. It can be used in outdoor coating additives to significantly reduce the fading of pigments caused by UV damage, etc.
