  • Epoxy resin-based autodeposition coatings
    Patent number: 6833398
    Abstract: Autodeposited coatings useful for protecting metal surfaces and in production of rubber-to-metal composites are obtained by curing adducts based on epoxy resins which are adhered to the metal surface. One or more epoxy resins, such as for example, the combination of a diglycidyl ether of bisphenol A and a flexibilizing epoxy resin, may be prereacted to form an adduct of higher average molecular weight than the starting epoxy resins. Said adduct may then be dispersed in water, with the resulting dispersion being used in an autodeposition bath composition.
    Type: Grant
    Filed: October 24, 2002
    Date of Patent: December 21, 2004
    Assignee: Henkel Kommanditgesellschaft auf Aktien
    Inventors: Rajat K. Agarwal, Brian D. Bammel, William E. Fristad, Gregg W. Rossier, Elizabeth J. Siebert, Zhiqi Yang
  • Method of forming rubber-metal composites
    Patent number: 6805768
    Abstract: A film of a polymer or polymer precursor such as an epoxy resin is autodeposited on an active metal surface and then used to form an adhesive bond directly between the metal surface and the surface of a rubber substrate. Excellent adhesion of the metal to the rubber is obtained without the need to either phosphate the metal surface or use a primer or adhesive other than the autodeposited coating.
