TTA can be used as corrosion inhibitor of copper, copper alloy and black metals. TTA 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 formation of TTA is more uniform. When used together with 2-Mercaptobenzoxtiazole (MBT), the effect is better.
