Abstract: When a phosphate ester or a dispersed wax is added to a conventional liquid phosphate conversion coating composition, the resulting phosphate coating formed on a metal substrate has a lower coefficient of friction after being oiled than it would have had if the additive had been omitted. The corrosion resistance and paint adhesion properties expected from the conversion coating are not substantially diminished by the additive. Particularly good results are achieved if the phosphate coating composition contains calcium and ferrous cations and the liquid phosphate conversion coating composition is dried into place on the substrate.
