Sodium Tolyltriazole, Tolytriazole Sodium Salt


Sodium tolyltriazole can be used as a corrosion inhibitor of copper and copper alloy. It also has corrosion inhibition for black metals.

Tolytriazole sodium salt is absorbed on the metal surface to form a thin membrane. This membrane can prevent copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. When used together with 2-Mercaptobenzothiazole, the effect is better.
