ABSTRACT:
Plasticized elastomer is securely bonded to a metal surface by interposing between the adhesive-coated metal surface and the elastomer a sheet of material obtained by combining adhesive with a portion of the elastomer that has been treated to remove plasticizers therefrom and heating the assembly in a mold under pressure. The sheet material is made up by dissolving a portion of the plasticized elastomer in an organic solvent, casting the solution, exposing it to a vacuum to remove the solvent and plasticizers, dissolving the de-plasticized material in liquid adhesive and casting and drying the resulting liquid.
