ABSTRACT:
There is disclosed a pressure-sensitive adhesive composition based on a silicone resin and a polydiorganosiloxane polymer wherein the resin component has a number average molecular weight of about 950 to 1,600 and consists essentially of triorganosiloxy (M) units and silicate (Q) units wherein the molar ratio M/Q is in the range 1.1/1 to 1.4/1, inclusive. The adhesives of the invention exhibit improved adhesion to low energy substrates such as polyethylene and polytetrafluoroethylene.
