Abstract
Disclosed is a process for the preparation of a composite including a room temperature vulcanizing silicone rubber and a chemically resistant polyester film which may be polyethylene terephthalate. The composite has particular utility as a part of medical equipment, for example as a component in an ultrasonic transducer. The susceptibility of the composite bond so formed to chemical challenge in the user environment is reduced or eliminated.
