RF2202 Zinc Butyl Octyl Primary Alkyl Dithiophosphate
Product Introduction:

RF2202 refers to Zinc Butyl Octyl Primary Alkyl Dithiophosphate (ZDDP). This product provides excellent anti-oxidation and anti-corrosion, and anti-wear and extreme pressure performance properties. It can effectively prevent engine bearing corrosion and oil viscosity increase due to high temperature oxidation. This product is light in color with good oil solubility and additive compatibility, widely used in various industrial lubricating oil applications like gear oil and hydraulic oil, as well as multiple grade engine oil formulation with the combination of detergent and dispersant. The recommended treat rate is 0.5%-3.0% (m%).
