Ⅱ. Performance and use
Copper corrosion inhibitor benzotriazole can be adsorbed on the metal surface to form a very thin film, protect copper and other metals from the atmosphere and harmful medium corrosion; Copper corrosion inhibitor BTA can be used in the circulating cooling water system in combination with a variety of scale inhibitors, bactericidal and algicidal agents. It has a good corrosion inhibition effect on the circulating cooling water system, and the amount of circulating water is 2-4mg/L. Copper corrosion inhibitor benzotriazole can also be used as antidiscoloration agent for copper and silver, automotive coolant, lubricant additives.
Ⅲ. Packaging and storage
Copper corrosion inhibitor benzotriazole is packaged in plastic drum, each drum is 25kg or according to customer's requirement. Store in a cool and dry place for six months. A small amount of precipitation at the bottom is normal after a long time storage. Shake well and use.
Ⅳ. Safety protection
