As a cornerstone of modern lubricant technology, Zinc Dialkyldithiophosphate (ZDDP) represents a class of multifunctional additives that have been protecting engines and machinery for decades. Our advanced ZDDP formulations, including the Zinc Butyl Octyl Primary Alkyl Dithiophosphate T202 and Zinc Dioctyl Primary Alkyl Dithiophosphate T203, are engineered to deliver exceptional anti-wear, antioxidant, and anti-corrosion performance. These carefully synthesized compounds, appearing as light yellow to transparent liquids, utilize optimized alkyl chain architectures (C8-C10) to balance surface activity with oil solubility. Meeting and exceeding stringent specifications such as MIL-PRF-2105E and DIN 51517, they provide comprehensive protection across temperatures ranging from -30°C to 180°C, making them indispensable components in high-performance lubricants for automotive, industrial, and specialized applications.
Superior Anti-Wear and Extreme Pressure Protection: ZDDP forms durable, sacrificial films on metal surfaces through tribochemical reactions, preventing direct metal-to-metal contact under high loads. This significantly reduces wear on critical components such as valve trains, gears, and bearings, with T202 demonstrating up to 60% reduction in wear scar diameter in Four-Ball tests.
Exceptional Oxidation Stability: These additives function as potent antioxidants by decomposing peroxides and terminating free radical chain reactions that lead to oil degradation. This oxidation inhibition can extend oil service life by up to 3 times, preventing sludge formation and viscosity increase while maintaining lubricant integrity under thermal stress.
Effective Corrosion Inhibition: The phosphorus-sulfur chemistry in ZDDP provides active protection against rust on ferrous metals and corrosion on copper-based alloys. This dual inhibition safeguards machinery during operation and storage, particularly in humid or corrosive environments.
Proven Reliability and Extended Equipment Life: With decades of field validation, ZDDP remains the most trusted anti-wear technology for protecting critical engine components and industrial machinery, significantly reducing maintenance costs and extending equipment service life.
Multifunctional Performance: ZDDP delivers three essential protective functions—anti-wear, antioxidant, and anti-corrosion—in a single additive, simplifying lubricant formulations while providing comprehensive protection against multiple failure modes.
Thermal Stability and Broad Operating Range: Our ZDDP variants maintain consistent tribological performance across a wide temperature spectrum (-30°C to 180°C), ensuring protection during cold starts and under severe thermal cycling conditions in demanding applications.
Emission System Compatibility: Advanced formulations like T202 feature zero-ash characteristics that eliminate catalytic converter fouling and diesel particulate filter blockage, making them ideal for modern emission-controlled vehicles while maintaining superior protection.
Engine Oils: Critical component in API CK-4 diesel oils and ILSAC GF-6A gasoline formulations for protecting valve trains, camshafts, and other high-stress engine components against wear and fatigue.
Industrial Gear Oils: Essential for wind turbine planetary gearboxes, mining conveyor drives, and steel mill reducers operating under extreme pressures exceeding 2GPa contact pressure.
Hydraulic Systems: Protects axial piston pumps in injection molding machines and hydraulic excavators experiencing operating pressures over 5,000 psi, preventing vane and pump wear.
Compressor Lubricants: Prevents vane tip scuffing in flooded screw compressors operating with HFC refrigerants, ensuring reliable operation and extended compressor life.
Technical Superiority and Performance Validation: Our T202 formulation demonstrates exceptional performance in independent testing, achieving 12-stage pass performance in FZG tests at 150°C—exceeding DIN 51517 requirements by 4 stages, providing verified protection under extreme conditions.
Optimized Molecular Design: The asymmetrical alkyl chain design in T202 enhances oil solubility and metal surface affinity, ensuring instantaneous film formation during shock loading events while maintaining compatibility with Group I-V base stocks and other additive systems.
Comprehensive Regulatory Compliance: Our ZDDP products come with complete technical documentation including HSE reports, REACH registration, and global automotive OEM approvals, providing formulators with confidence for worldwide marketing and application.
Cost-Effective Protection: The multifunctional nature of ZDDP reduces the need for multiple single-function additives, providing comprehensive protection at competitive pricing while extending lubricant and equipment life for superior total cost of ownership.
ZDDP remains an essential, irreplaceable component in modern lubricant technology, providing proven protection against wear, oxidation, and corrosion that has stood the test of time. Our advanced ZDDP formulations, T202 and T203, build upon this legacy with optimized chemistry that meets contemporary demands for emission system compatibility, enhanced thermal stability, and verified extreme pressure performance. By choosing our ZDDP additives, you select a partnership dedicated to delivering scientifically advanced, reliable, and compliant solutions that protect critical equipment across automotive, industrial, and specialized applications, ensuring optimal performance and extended service life in the most challenging operating environments.
