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.
