ZP-102L
Zinc dialkyldithiophosphate — primary C8, oil-free
Oil-free primary C8. Combines the hydrolytic stability of the C8 chemistry with full formulation freedom — the grade additive-package houses ask for.

Grades a formulator would benchmark ZP-102L against. Naming them is not a claim of equivalence — it is where to start the comparison.
Zinc Dialkyldithiophosphates
Antiwear, antioxidant and corrosion inhibitor in one molecule
Still the most cost-effective antiwear chemistry ever commercialised. Primary alkyl ZDDPs are thermally more stable and preferred in industrial and heavy-duty applications; secondary alkyls decompose at lower temperature and film faster, which is why they dominate passenger-car engine oils. Alcohol chain length sets both the thermal stability and the hydrolytic stability.
Engine Oils
Passenger-car, heavy-duty and gas engine crankcase formulations, including low-SAPS.
Industrial Gear Oils
Enclosed gear drives, wind turbine gearboxes and heavy industrial reducers.
Hydraulic Fluids
Anti-wear hydraulic oils, including zinc-free and fire-resistant fluids.
Driveline & Transmission
Automatic and manual transmission fluids, axle oils, EV reduction-gear fluids.
