  • Method of attaching a strip to a rubber molded part
    Patent number: 6238787
    Abstract: A method of attaching to a rubber molded part a strip having an acrylic polymer adhesive on one side, including the step of applying radio frequency energy to the rubber molded part to generate heat therein and to cause the acrylic polymer adhesive to melt bond to the rubber molded part. The acrylic polymer is an acrylic-silane interpolymer of primarily acrylic ester monomer interacted with an organosilane, which interpolymer has a Tg of −10° to 80° C. The rubber molded part includes radio frequency sensitive material to facilitate bonding to the acrylic polymer adhesive during application of the radio frequency energy thereto. Desirably, the strip also includes a pressure sensitive adhesive on its other side for securing the rubber part to a component of an automobile or other vehicle by applying pressure to the rubber part. The strip may include an acrylic foam core between the acrylic polymer adhesive and the pressure sensitive adhesive.
