Abstract
A powder primer composition particularly useful as a primer intended to be used in conjunction with an adhesive topcoat in rubber to metal bonding. And a method for bonding an elastomeric substrate to a metallic substrate comprising, applying a powder primer composition onto one of said substrates, wherein the powder primer composition comprises a rubbery polymer and at least one of a phenolic resin and a phenoxy resin, applying an adhesive covercoat to form a coated substrate, contacting the coated substrate with the other of said substrates, and heating the contacted substrates to effect bonding of the metallic substrate to the elastomer.
