Tolyltriazole (TTA) (CAS NO : 29385-43-1)

Tolyltriazole (TTA) is a methyl-substituted benzotriazole derivative used as a corrosion inhibitor, particularly for copper and copper alloys. It forms a stable, adsorbed protective film on metal surfaces in cooling water systems, hydraulic fluids, lubricants, and antifreeze formulations. TTA is valued for its thermal stability, metal affinity, and low volatility, making it a go-to additive in closed-loop systems and industrial water treatment.
