ZP-101H

Zinc dialkyldithiophosphate — primary C4/C8, oil-free

The undiluted version of ZP-101. No carrier oil means maximum active content and full freedom over which base stock the blender dilutes into — relevant for PAO, ester and food-grade work where a mineral carrier is unacceptable.

Cross-reference

Grades a formulator would benchmark ZP-101H against. Naming them is not a claim of equivalence — it is where to start the comparison.

The chemistry

Zinc Dialkyldithiophosphates

Antiwear, antioxidant and corrosion inhibitor in one molecule

Typical treat rate0.5 – 1.5 %

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.
