The coating composition provides a controlled delivery of phosphate anions of 100 to 1,500 ppm, depending on post-formation treatment of the aluminum phosphate, and has a total solubles content of less than 1500 ppm, The amorphous aluminum phosphate is free of alkali metals and alkaline earth metals, and has a water adsorption potential of up to about 25 percent by weight water when present in a cured film.Type: GrantFiled: October 15, 2010Date of Patent: April 14, 2015Assignee: Bunge Amorphic Solutions LLCInventor: Raymond E.

Patent number: 8956468Abstract: The invention relates to an aqueous composition and to a method for the anticorrosion conversion treatment of metallic surfaces, particularly metallic materials which are assembled into composite structures, comprising steel or galvanized or alloy-galvanized steel and any combinations thereof, the composite structure being composed at least in part of aluminum or the alloys thereof. The aqueous composition according to the invention is based on a phosphating solution and contains, in addition to water-soluble compounds of zirconium and titanium, a quantity of free fluoride in a ratio that both permits phosphating of the steel and galvanized and/or alloy-galvanized steel surfaces and determines low pickling rates of the aluminum substrate with simultaneous passivation of the aluminum.Type: GrantFiled: March 19, 2012Date of Patent: February 17, 2015Assignee: Henkel AG & Co.

Patent number: 8951363Abstract: The invention refers to a process for producing an anticorrosive coating in which a surface to be treated is brought into contact with an aqueous treatment solution containing chromium(III) ions and at least one phosphate compound and an organosol. The corrosive protection of metal surfaces, in particular those containing zinc and zinciferous surfaces with conversion layers is improved. The decorative and functional properties of the surfaces are retained or improved. In addition, the well-known problems associated with the use of compounds containing chromium(VI) or with multi-stage processes are avoided in which a passivation layer containing chromium ions and a sealing are applied one after the other.Type: GrantFiled: July 5, 2010Date of Patent: February 10, 2015Assignee: Atotech Deutschland GmbHInventors: Udo Hofmann, Hermann Donsbach, Joerg Unger, Volker Krenzel
