Multi-Functional Lubricant Additive ZDDP For Antiwear Antioxidant
ZDDP (Zinc Dialkyldithiophosphate)
ZDDP is a multifunctional lubricant additive appearing as a pale yellow transparent liquid with a characteristic sulfur-phosphorus odor. With an active ingredient content of 90-95% zinc dialkyldithiophosphate, this classical additive is widely used in internal combustion engine oils, hydraulic oils, and gear oils. It forms protective films on metal surfaces to enhance anti-wear, antioxidant, and anti-corrosion properties.

Performance and Applications
Extreme Pressure Anti-Wear: Forms protective films on friction surfaces under high temperature/pressure conditions, reducing metal-to-metal contact and extending component lifespan in engines, transmissions, and gearboxes.
Oxidation Resistance: Captures free radicals to delay oil aging, prevent sludge formation, and maintain lubrication system cleanliness while extending oil drain intervals.
Corrosion Protection: Safeguards non-ferrous metals (copper, lead, babbitt) by neutralizing acidic substances, making it ideal for both industrial and automotive lubricant formulations.
Key Advantages
Multi-functional protection combining extreme pressure anti-wear, antioxidant, and anti-corrosion properties
Proven technology with high cost-effectiveness and extensive industry validation
One of the most widely used and reliable lubricant additives available
