Product Overview
T561 is a high-performance, liquid, ashless metal deactivator that functions as an oil-soluble thiadiazole derivative. It combines exceptional copper corrosion inhibition with outstanding extreme-pressure and auxiliary antioxidant properties. Even at extremely low addition concentrations, T561 effectively suppresses the corrosive effects of active sulfur on copper and copper alloy components, delivering superior performance. Widely used in various automotive and industrial lubricants as well as metalworking fluids, T561 serves as a critical additive for enhancing the overall protective performance of lubricating oils.
Performance Characteristics
① Ash-free formulation design: Utilizing an ash-free formula significantly reduces deposit formation, enhances lubrication efficiency, and minimizes environmental impact.
② Exceptional Copper Corrosion Inhibition: Effectively neutralizes active sulfur at extremely low concentrations, thereby preventing its corrosive effects on copper and copper alloys. Simultaneously addresses hydrolytic stability issues and mitigates copper corrosion caused by additives such as organic molybdenum compounds. This ensures robust protection of critical components, significantly reducing the risk of equipment failure due to corrosion.
③ Multifunctional Extreme Pressure Protection: Provides robust extreme pressure performance for lubricants and metalworking fluids, significantly enhancing wear protection under high-pressure and heavy-load conditions, thereby effectively extending the service life of mechanical components.
④ Efficient antioxidant assistance: Effectively inhibits the formation of oxidation byproducts such as sludge and varnish, maintaining stable lubricant performance, thereby extending oil change intervals and reducing equipment maintenance costs.
⑤ Excellent oil solubility compatibility: Demonstrates outstanding solubility in base oils and composite formulations, synergistically enhancing performance when combined with additives such as anti-wear agents and antioxidants.
Scope of Application
Applied to industrial lubricants, automotive lubricants, metalworking fluids, and greases.
