    Application:

    The main application of ZDDPs are as anti-wear additives in lubricants including greases, hydraulic oils, and motor oils. ZDDPs also act as corrosion inhibitors and antioxidants. They are almost ubiquitous in lubricants and treatment rates are usually between 600 ppm for modern, energy conserving low viscosity oils to 2000 ppm of this additive in some racing oils.
