A bonded part such as a rubber to metal bonded part and process for producing a bonded part including a rubber and metal part, and particularly for producing an automotive torsional vibration damper, comprising the steps of placing uncured elastomer composition comprising an elastomer, at least one curative, and preferably, at least one rubber-to-metal adhesive adjuvant into a shape-forming mold, and curing the elastomer in two stages, wherein in the first curing stage the elastomer composition is less than fully cured and in the second curing stage, preferably performed with the elastomer composition in contact with a metal surface of the rubber and metal part, the elastomer composition is at least substantially fully cured. According to one embodiment, the present invention allows for the elimination of the step of applying an adhesive to the metal surface prior to application of the elastomer composition.
A process for forming a bonded part comprising a rubber member and at least one of a first outer member and a second outer member, comprising the steps of:
A process for forming a torsional vibration damper comprising a cured elastomer composition, a first metal surface and a second metal surface, comprising the steps of:
A rubber-to-metal bonded article, comprising at least a first metal member, a second metal member and a cured rubber member disposed between and bonded to at least one of said first metal member and said second metal member, wherein:
