A powder adhesive comprising a primary rubber bonding polymer and a thermosetting component, and a method for bonding elastomers to metals employing the same. By adding a thermosetting component to a powdered adhesive, the adhesive may be applied to a substrate, sintered and thermoset to provide a sweep resistant adhesive film on the substrate, which may subsequently be bonded to an elastomer. Without a thermosetting component, the adhesive is at risk to re-melt or otherwise soften during a heated elastomer molding operation which in turn could cause the adhesive material to sweep off the substrate. |
