Product Overview
T561 is an ashless, multifunctional liquid additive. As a thiazole‑dithiol derivative, it exhibits excellent copper‑corrosion inhibition, effectively protecting copper and copper‑alloy components from corrosion caused by active sulfur. It also boasts superior oil solubility and auxiliary antioxidant properties, making it widely suitable for various automotive and industrial lubricants as well as metalworking fluids. T561 is a key additive for enhancing the overall protective performance of lubricants.
Performance Features
① Ashless formulation design: reduces the risk of deposit formation, optimizes lubrication efficiency, and minimizes environmental impact.
② Excellent copper corrosion inhibition: Effectively neutralizes the corrosive activity of sulfur, protecting critical components.
③ High-efficiency metal deactivation: neutralizes the catalytic oxidation activity of copper and iron ions, thereby extending the service life of the lubricant.
④ Synergistic antioxidant action: inhibits oxidation and degradation of lubricants, reduces sludge formation, and extends oil-change intervals.
⑤ Excellent oil‑solubility compatibility: Exhibits outstanding solubility in base oils and formulated blends, ensuring formulation stability.
Scope of Application
① Industrial lubricants: gear oils, hydraulic oils, compressor oils, and turbine oils.
② Automotive lubricants: engine oil, gear oil, and transmission fluid.
③ Metalworking fluids: cutting fluids, grinding fluids, and forming fluids.
④ Lubricating Greases: industrial lubricating greases, automotive lubricating greases.
⑤ Specialty oils: transformer oil, fuel additives.
