? Methyl-1h-benzotriazole , with CAS number of 29385-43-1, can be called 1H-1,2,3-benzotriazole, 4-methyl- ; 1H-Benzotriazole, 4(or 5)-methyl- ; 249-921-1 [EINECS/ELINCS] ; 1H-benzotriazole, 4-methyl- .? Methyl-1h-benzotriazole (CAS NO.29385-43-1) is mainly for metals (silver, lead, nickel, zinc, copper and copper metal) inhibitor and anti-rust agents, widely used in anti-rust oil (ester) products, used for copper and copper alloy vapor corrosion inhibitors, Circulating water treatment agent, lubricant additives. Methyl-1h-benzotriazole (CAS NO.29385-43-1) can also scale with a variety of agents, biocide used in conjunction with, especially for circulating cooling water system corrosion is very good.?
?Methyl-1h-benzotriazole (CAS NO.29385-43-1) can be used as corrosion inhibitor of copper and copper alloy, it also has corrosion inhibition for black metals. This product is absorbed on metal surface to form a thin membrane to protect copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. When used together with MBT, the effect is better.
