Sulfate Propyl Octyl Secondary Alkyl Zinc Salt Zddp Additives
Ultra-Stable Anti-Wear Agent for High-Temperature & Biohydraulic Systems
Premium Zinc Additive for Motor Oil Protection
This premium zinc additive for motor oil has excellent antioxidant & corrosion resistance properties, and can effectively solve the wear and corrosion of cam and follower and the viscosity increase brought by high-temperature oxidation. As a specialized zinc additive for motor oil, it has good oil solubility, and is suitable for blending high grade gasoline engine oil.
Product Introduction
This Sulfate Propyl Octyl Secondary Alkyl ZDDP redefines thermal stability with its unique branched-chain architecture. Engineered for >200°C operating environments, this zinc additive for motor oil delivers uncompromising wear protection while resisting hydrolysis in biohydraulic and food-contact applications where conventional ZDDP fails.
Advanced Technologies
- Thermal Armor Technology™
Maintains anti-wear properties at 220°C (40% better than primary ZDDP, ASTM D4172 modified).
- Hydrolytic Immunity
<2% hydrolysis after 500h at 90°C/10% water (ASTM D2619).
- Bio-Oxidation Resistance
5x oxidation life extension in vegetable oil bases (RPVOT ASTM D2272).
- Extreme Pressure Fortification
Achieves 650 kg weld load (FZG A/16.6/90 Stage 15).
- Food Safety Compliance
<0.1 ppm heavy metal leaching (FDA 21 CFR §178.3570).
