Abstract
Abstract A rubber bondable metal surface is pretreated by coating it with an organic oil mixture and rubbing it with a slightly abrasive material prior to adhering the treated metal to a natural or synthetic rubber. The adhering of the metal to rubber is accomplished by merely heating the rubber to bond it to the pretreated metal or by also adding a coating of adhesive between the pretreated metal and rubber and curing the composite to bond the adhesive contacting surfaces.
