Abstract

This invention is related to the use of moderately branched but primarily linear polydimethyl siloxane fluids as release agents on the heat roll of a xerographic labeling machine. In such a machine, heat and pressure are applied on the face of the label to activate the heat-sensitive adhesive which is coated on the back of the label. The heat and pressure cause adhesive-coated labels to adhere to the mailing envelopes. During this process, the address on the face of the label, which is a toner image produced by a xerographic process, is in contact with the heat roll and may be damaged thereby. The moderately branched, primarily linear polydimethyl siloxane fluids of the present invention serve as release agent on the heat roll to permit the application of heat and pressure without significantly disturbing the toner image. An example of the release agents of the present invention is:
