Publication number: 20030082391Abstract: A multilayered coating (10) that is applied to a metal substrate (12). The coating comprises a protective zone of an insoluble crystalline phosphate formed by reaction of the substrate (12) with zinc phosphate. A film (16) of a polymer resin is deposited on the insoluble crystalline phosphate zone (14). In one embodiment, the multilayered coating (10) includes a coat of paint (18) that is applied to the polymer resin (16). A process for applying the multilayered coating to the metal substrate includes the steps of: applying a zinc phosphating solution to at least a portion of the substrate, which converts the surface to a zone of an insoluble crystalline phosphate; rinsing the zone; and autodepositing a film of a polymer resin thereupon.Type: ApplicationFiled: April 8, 2002Publication date: May 1, 2003Applicant: Henkel CorporationInventors: Bruce H.

Patent number: 6478885Abstract: 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.Type: GrantFiled: November 8, 2000Date of Patent: November 12, 2002Assignee: Henkel CorporationInventor: Bruce H.
