Zinc Dialkyl Dithiophosphate Lubricant Antiwear Additive ZDDP
Product Spotlights
AD-202HT ZDDP(Zinc Dialkyl Dithiophosphate)/Zinc Butyl Octyl Primary Alkyl Dithiophosphate
Description
AD-202HT(ZDDP is short for Zinc Butyl Octyl Primary Alkyl Dithiophosphate) is an extremely potent, cost-effective antioxidant and corrosion inhibitor and deemed as essential in today’s automotive lubricating oils.AD-202HT(ZDDP) could provide the oils with excellent antioxidation, anticorrosion performances and strong extreme pressure, anti-wear abilities. AD-202HT(ZDDP) can efficiently prevent the engine bearings from corrosion, and also prevent the viscosity of the oils from increasing due to the high-temperature oxidation. AD-202HT(ZDDP) is recommended for use in blending industrial lubricating oils such as gear oils, hydraulic oils, etc. It can be used for blending middle-grade engine oils combined with detergents and dispersants.
Application
◎ Use in industrial lubricating oils including gear oils, hydraulic oils, etc
◎ Use in middle-grade engine oils
◎ Recommended dosage:0.5-3.0%
