Overview
XLF-13H+ is a premium lubricant additive formulated to address extreme-pressure and high-temperature challenges in modern machinery. Developed for industrial and automotive applications, it chemically bonds to metal surfaces, forming a protective layer that reduces friction and prevents component wear. Unlike conventional additives, XLF-13H+ maintains effectiveness across a broad temperature range (-30°C to 300°C), making it suitable for demanding environments like mining equipment, wind turbines, and high-performance engines. Its multifunctional design combines anti-wear, antioxidant, and corrosion inhibition properties in a single compound.
Physical and Chemical Properties
XLF-13H+ exhibits a viscosity of 120-150 cSt at 40°C, with a flash point exceeding 180°C. Its sulfur-phosphorus-nitrogen compound structure enables synergistic performance enhancements when blended at 1-3% concentration in base oils. The additive demonstrates exceptional hydrolytic stability, resisting breakdown in humid conditions. Laboratory tests show it reduces wear scar diameter by 60-70% in Four-Ball Wear Tests (ASTM D4172) compared to untreated oils. Its thermal decomposition begins at 200°C, gradually releasing active elements that regenerate protective surface films.
Main Applications
Primary use cases include heavy-duty diesel engine oils (API CJ-4/CK-4 specifications), where it helps meet phosphorus retention requirements while controlling soot-induced viscosity increase. In industrial settings, it's formulated into gear oils for cement mixers and crushers operating under shock loading conditions. Advanced applications include wind turbine gearboxes, where its long-term stability reduces maintenance intervals. Some synthetic lubricant manufacturers incorporate XLF-13H+ at higher concentrations (up to 5%) for specialized metalworking fluids, particularly in titanium and nickel alloy machining operations.
Safety and Storage
While classified as non-hazardous under normal conditions, XLF-13H+ requires handling precautions due to potential skin irritation. Facilities should maintain spill containment measures and use chemical-resistant gloves (nitrile or neoprene recommended) during transfer operations. Storage in original HDPE containers prevents contamination. Bulk tanks should be nitrogen-purged to minimize oxidation. The additive has a shelf life of 24 months when stored below 40°C without water ingress. Disposal should follow local regulations for organic chemical products, with incineration being the preferred method.
B2B Procurement Guide
Industrial buyers should evaluate suppliers based on batch consistency certifications (ISO 9001 compliance), technical support capabilities, and regional logistics networks. Request sample testing with your specific base oil blend to confirm performance metrics like Timken OK Load and Sequence IIIG engine test results. Consider total cost of ownership rather than unit price—higher-quality additives often allow extended drain intervals. Negotiate pricing tiers for annual contracts exceeding 5 metric tons. For international shipments, verify Harmonized System (HS) code classification to ensure smooth customs clearance, typically under 3811.19.00 for prepared additive packages.
