Zinc Dialkyldithiophosphates Properties

Zinc Dialkyldithiophosphates



Zinc dialkyldithiophosphates are a family of coordination compounds invented by Castrol that feature zinc bound to the anion of dithiophosphoric acid. These uncharged compounds are not salts. They are soluble in nonpolar solvents, and the longer chain derivatives easily dissolve in mineral and synthetic oils used as lubricants. The main use of ZDDP is in anti-wear additives to lubricants such as greases, gear oils, and motor oils. It serve also as corrosion inhibitors and antioxidants.
