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.

Chemical Properties & Specifications
Primary use in cooling water systems, heat exchangers, and closed-loop circulation units.
Prevents copper tarnish and discoloration in metal cleaners, lubricants, and cutting fluids.
Used in antifreeze formulations (ethylene glycol-based) to protect engine parts.
Stabilizes copper surfaces during electroplating and PCB manufacturing.
Primarily copper and its alloys, also extends protection to aluminum and steel when blended.
Yes. It is stable in ethylene/propylene glycol and used in both automotive and HVAC fluids.
TTA has a methyl group substitution, offering slightly better solubility and stability at elevated temperatures.
Yes, when dosed correctly and monitored with polymer dispersants.
Yes. Available in flakes, fine powder, and granular grades, depending on end-use.
COA, MSDS, REACH registration support, and product stability data are available.
