This multifunctional additive meets and exceeds stringent industrial specifications including MIL-PRF-2105E and DIN 51517, enhancing operational durability across extreme-pressure environments. Its thermally stable molecular architecture maintains consistent tribological performance across temperatures ranging from -30°C to 180°C, making it indispensable for modern lubrication systems operating under severe thermal cycling conditions.
Superior Anti-Wear Protection: Forms chemically bonded sacrificial films on ferrous surfaces through tribochemical reactions, reducing wear scar diameter by 60% in Four-Ball tests.
Exceptional Oxidation Stability: Incorporates synergistic peroxide decomposers that extend oil service life by 3x through radical scavenging mechanisms.
Zero-Ash Formulation: Eliminates catalytic converter fouling and diesel particulate filter blockage in emission-controlled vehicles.
Dual Corrosion Inhibition: Phosphorus-sulfur chemistry provides active protection against rust (ASTM D665) and copper corrosion (ASTM D130).
Boundary Friction Reduction: Polarity-enhanced molecules reduce friction coefficients by 45% in Cameron-Plint tribometer evaluations.
Universal Compatibility: Stable colloidal dispersion in Group I-V base stocks and common additive systems including detergents and dispersants.
Industrial Gear Oils: Critical component for wind turbine planetary gearboxes, mining conveyor drives, and steel mill reducers operating under >2GPa contact pressure.
Hydraulic Systems: Protects axial piston pumps in injection molding machines and hydraulic excavators experiencing >5,000 psi operating pressures.
Engine Oils: Supplemental anti-wear agent in API CK-4 diesel oils and ILSAC GF-6A gasoline formulations for valve train protection.
Rotary Compressor Lubricants: Prevents vane tip scuffing in flooded screw compressors operating with HFC refrigerants.
T202 outperforms conventional zinc dialkyldithiophosphate (ZDDP) additives by eliminating phosphorus-induced catalyst poisoning while delivering superior extreme-pressure performance. Its asymmetrical alkyl chain design enhances oil solubility and metal surface affinity, ensuring instantaneous film formation during shock loading events. Independent FZG testing validates 12-stage pass performance at 150°C bulk oil temperature - exceeding DIN 51517 requirements by 4 stages. For lubricant formulators balancing OEM warranty compliance with field-proven protection, T202 delivers a future-proof solution with comprehensive technical documentation including HSE reports, REACH registration, and global automotive OEM approvals.
