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.
