【Product properties】
Tolyltriazole (TTA) is a mixture of 4-methylbenzotriazole and 5-methylbenzotriazole, available as white to light yellow granules or powder. TTA has a melting point of 80–86°C. It is sparingly soluble in water, but readily soluble in alcohol, benzene, toluene, chloroform, and other organic solvents, as well as in dilute alkali solutions. With a high purity level, TTA delivers consistent and reliable performance for demanding applications.
【Storage】
Tolyltriazole (TTA) should be stored in tightly sealed containers, kept in a cool, dry, and well-ventilated warehouse, protected from heat, moisture, and strong oxidizing agents.
【Packing】
Available in 20 kg, 25 kg, and 500 kg net packaging options, including valve bags, fiber drums, and FIBC flexible intermediate bulk containers. Customized packaging is available upon request.
【Application】
Tolyltriazole (TTA) is a high-performance corrosion inhibitor with broad industrial utility:
Corrosion inhibitor for metals – TTA is an effective rust preventive and corrosion inhibitor for silver, copper, lead, nickel, zinc, and other metals, widely used in rust preventive oils and greases.
Vapor phase corrosion inhibitor – TTA is specially used as a vapor phase corrosion inhibitor for copper and copper alloys in enclosed systems.
Lubricant additive – TTA is used as an additive in lubricating oils to protect metal surfaces from corrosion.
Circulating water treatment – TTA is employed in cooling water treatment formulations and automotive antifreeze fluids.
Synergistic formulations – TTA can be used in combination with various scale inhibitors and biocides, delivering excellent corrosion inhibition performance, particularly in closed-loop cooling water systems.
