Patents by Inventor Gordon P Bierwagen

Gordon P Bierwagen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9103040
    Abstract: Disclosed are methods of treating a metal to improve the metal's corrosion resistance. The method includes applying, to the surface of the metal, a coating which comprises magnesium powder and a binder. The present invention also relates to a coating composition that includes magnesium powder and a silane modified epoxy isocyanate hybrid polymer or prepolymer. The inventors have found that corrosion resistance (as determined by Prohesion™ exposure in accordance with ASTM D5894-96, which is hereby incorporated by reference) in excess of 3,000 hours on 2024 T-3 aluminum alloy can be achieved with the methods and coating compositions of the present invention.

  • Publication number: 20150218411
    Abstract: Disclosed are methods of treating a metal to improve the metal's corrosion resistance. In one such method, the method is carried out by applying, to the surface of the metal, a coating which includes magnesium powder and a UV-curable or other radiation-curable binder. In another such method, the method is carried out by applying, to the surface of the metal, a coating which includes magnesium powder and an inorganic binder. In another such method, a coating that includes a magnesium alloy powder and a binder is applied to the surface of the metal. The magnesium alloy powder is selected such that it has a corrosion potential that is from about 0.01 volt to about 1.5 volt more negative than the metal's corrosion potential. Also disclosed are methods of treating a ferrous metals and magnesium alloys to improve the corrosion resistance of these materials.
