RD202/RD203 Zinc Dioctyl Dithiophosphate RD202 is a zinc thiophosphate, which is prepared from thiophosphoric acid made from butyl octyl alcohol. When added into oils, it can inhibit oil oxidation. It has antioxidation, antiwear and corrosion proof.

ZINC DITHIOPHOSPHATE is a darkcolored viscous liquid with a mild odor. Insoluble in water and slightly less dense than water. Contact may moderately irritate skin, eyes, and mucous membranes, and cause dizziness, nausea and loss of consciousness. Used to make other chemicals and is a marine pollutant.
