Sodium tolyltriazole

Sodium tolyltriazole (CAS 64665-57-2), also marketed as Cobratec TT50S and Cobratec TT85 and abbreviated TTA-Na, is a water-soluble corrosion inhibitor and metal deactivator for industrial fluid systems.

Where is Sodium tolyltriazole used?

• Water treatment: dosed in cooling towers and closed-loop circuits to protect copper alloy components from corrosion and pitting
• Lubricants and metalworking fluids: metal deactivator preventing copper catalysis of oil oxidation
• Automotive antifreeze and coolants: non-ferrous metal corrosion inhibitor meeting OEM specifications
• Hydraulic fluids and industrial cleaners: copper and brass component protection
• It forms a stable protective complex on copper, brass, and other non-ferrous metal surfaces, preventing oxidative attack in aqueous and oil-based environments.

Commercial specifications

• Aqueous solution with 50% and 85% active content
• Bulk liquid in drums and IBC containers
