Tolyltriazole Sodium Salt, TTA·Na


Tolyltriazole sodium salt can be used as a corrosion inhibitor of copper and copper alloy. It also has corrosion inhibition for black metals. TTA·Na is absorbed on the metal surface to form a thin membrane. This membrane can protect copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. The effect is better when used together with MBT.
