Description

Tolytriazole Sodium Salt CAS NO 64665-57-2 is the sodium salt derivative of tolyltriazole, a high-performance corrosion inhibitor and metal deactivator. This compound is valued for its superior solubility in aqueous systems compared to the free acid form, enabling more efficient formulation and application. It is primarily utilized by industries requiring robust protection for copper and copper alloy components against tarnishing and corrosion in cooling water systems, hydraulic fluids, and metalworking fluids.

Application

• Cooling Water Treatment: A key additive in open and closed recirculating cooling water systems to protect heat exchangers, condensers, and piping made from copper and its alloys.
• Metalworking Fluids: Incorporated into synthetic and semi-synthetic fluids to prevent corrosion and staining of copper-containing workpieces and machine parts.
• Hydraulic & Industrial Lubricants: Functions as a copper corrosion inhibitor and metal deactivator in lubricating oils and hydraulic fluids to enhance system longevity.
• Antifreeze & Coolants: Used in automotive and industrial coolant formulations to protect radiator solders and other copper components from corrosive degradation.
• Paint & Coating Additive: Serves as a corrosion inhibitor in primers and coatings designed for metal substrates, including mixed-metal assemblies.
• Plating & Surface Treatment: Employed in electroplating baths and pickling solutions to minimize corrosive attack on copper surfaces.
