20090032144PRETREATMENT COMPOSITIONS AND METHODS FOR COATING A METAL SUBSTRATE - Disclosed are methods for treating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods include contacting the substrate with a pretreatment composition that includes: (a) a group IIIB and/or IVB metal; (b) free fluorine; (c) a metal fluoride salt formed from a metal which forms a fluoride salt having a pK02-05-2009
20090084682METHODS FOR COATING A METAL SUBSTRATE AND RELATED COATED METAL SUBSTRATES - Disclosed are methods for treating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods include depositing an electropositive metal onto at least a portion of the substrate, and then contacting the substrate with a pretreatment composition that is substantially free of crystalline phosphates and chromates. The present invention also relates to coated substrates produced thereby.04-02-2009
20100047583AUTOMOTIVE SUBSTRATE HAVING A COATING LAYER SYSTEM WITH A BARRIER COATING COMPOSITION LAYER - An automotive substrate comprising an electrodepositable coating layer deposited over at least a portion of the automotive substrate and a barrier coating layer deposited over at least a portion of the electrodepositable coating layer.02-25-2010
20100159258METHODS FOR PASSIVATING A METAL SUBSTRATE AND RELATED COATED METAL SUBSTRATES - Disclosed are methods for passivating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods comprise the steps of depositing an electropositive metal onto at least a portion of the substrate, followed immediately by electrophoretically depositing on the substrate a curable, electrodepositable coating composition. The present invention also relates to coated substrates produced by the above methods.06-24-2010
20100187117ELECTRODEPOSITABLE COATING COMPOSITION COMPRISING SILANE AND YTTRIUM - An electrodepositable coating composition comprising (i) a film-forming polymer, (ii) a corrosion inhibitor, and (iii) a silane that does not contain an ethylenically unsaturated double bond.07-29-2010
20100243108METHOD FOR TREATING AND/OR COATING A SUBSTRATE WITH NON-CHROME MATERIALS - The present invention is directed to a method for coating a substrate comprising: (a) applying a caustic cleaner onto at least a portion of the substrate; (b) rinsing at least a portion of the substrate that was subjected to step (a) with water; (c) applying an acid cleaner onto at least a portion of the caustically cleaned substrate; (d) rinsing at least a portion of the substrate that was subjected to step (c) with water; and (e) applying a conversion coating comprising zirconium onto at least a portion of the acid cleaned substrate; and wherein at least one of the materials used in steps (c) and (e) is substantially chrome free. The present invention is also directed to a substrate, such as an aluminum substrate, that has been coated using the aforementioned method.09-30-2010
20100285334METHODS FOR PASSIVATING A METAL SUBSTRATE AND RELATED COATED METAL SUBSTRATES - Disclosed are methods for passivating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods comprise the steps of autodepositing copper, silver, a IIIB metal and/or IVB metal onto at least a portion of the substrate, and simultaneously and/or immediately subsequently electrophoretically depositing on the substrate a curable, electrodepositable coating composition; wherein the copper, silver, IIB metal and/or IVB metal and the curable, electrodepositable coating composition are both contained within a single bath composition. The present invention also relates to coated substrates produced by the above methods.11-11-2010
20110008625ELECTRODEPOSITION COATINGS INCLUDING A LANTHANIDE SERIES ELEMENT FOR USE OVER ALUMINUM SUBSTRATES - A process for applying a coating on aluminum substrates by anionic or cationic electrodeposition of an electrodeposition coating including an aqueous dispersion of one or more lanthanide series elements having a +3/+4 oxidation state and phosphated epoxy resin made by phosphating a polyepoxide with both phosphoric acid and an organophosphonic acid and/or an organophosphinic acid. The coating has a reduced tendency to form pinholes.01-13-2011
20110083580REPLENISHING COMPOSITIONS AND METHODS OF REPLENISHING PRETREATMENT COMPOSITIONS - Disclosed are replenisher compositions and methods of replenishing pretreatment compositions. The methods include adding a replenisher composition to a pretreatment composition wherein the replenisher composition includes: (a) a dissolved complex metal fluoride ion wherein the metal ion comprises a Group IIIA metal, Group IVA metal, Group IVB metal, or combinations thereof; (b) a component comprising an oxide, hydroxide, or carbonate of Group IIIA, Group IVA, Group IVB metals, or combinations thereof; and optionally (c) a dissolved metal ion comprising a Group IB metal, Group IIB metal, Group VIIB metal, Group VIII metal, Lanthanide Series metal, or combinations thereof.04-14-2011
