Zinc Butyl Octyl Primary Alkyl Dithiophosphate Zddp Additive T202
Advanced Primary ZDDP Anti-Wear Agent for Modern Engines
T202 has good anti-oxidation, anti-corrosion and extreme pressure resistance, and can effectively prevent engine bearing corrosion and oil viscosity increase due to high temperature wear and oxidation. This product is light in color, has good oil solubility and additive compatibility. This product is widely used in a variety of industrial lubricants such as gears and hydraulic oils, and can be used in combination with detergent dispersants to prepare mid-range engine oils.
Product Introduction
T202 is a premium primary alkyl zinc dialkyldithiophosphate (ZDDP) engineered to deliver exceptional anti-wear, antioxidant, and anti-corrosion protection in high-stress lubrication systems. Utilizing butyl/octyl primary alcohol chemistry, it provides superior thermal stability and compatibility with emission control systems. Key applications include passenger car engine oils, hydraulic fluids, and industrial gear lubricants requiring extended component life.
- Enhanced Anti-Wear Performance
Forms robust tribofilms on metal surfaces, reducing wear by 70%+ in ASTM D4172 Four-Ball tests.
- Primary Alkyl Advantage
Butyl/octyl structure offers 30% higher thermal stability vs. secondary ZDDP (per ASTM D2893).
- Oxidation Inhibition
Extends oil life 2x longer by neutralizing free radicals (ASTM D943 oxidation test).
- Low-Impact Formulation
Controlled phosphorus (≤0.08% in finished oil) protects catalytic converters.
- Multi-Metal Protection
Prevents copper corrosion (ASTM D130 Rating 1a) and bearing rust (ASTM D665).
