Zinc dialkyldithiophosphates (often referred to as zddp) are a family of coordination compounds 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. They come under CAS number [68649-42-3]. In aftermarket oil additives, the percentage of zddp ranges approximately between 2-15%.

Applications
The main use of zddp is in anti-wear additives to lubricants such as greases, gear oils, and motor oils, which contain about 1%. For applications in oils for gasoline engines, zinc and phosphorus emissions could damage catalytic converters and have had their quantity reduced in standard formulations. Aftermarket additives are available. The same compounds serve also as corrosion inhibitors and antioxidants.

We are looking forward to build sincere and long-term business relationships with you.
