Abstract
A pressure sensitive adhesive composition which contains a mixture of a silicate resin, a polyorganosiloxane fluid, and a polyisobutylene polymer having at least one functionalized silicon containing moiety. One advantage of the present invention is that it provides a silicone pressure sensitive adhesive composition that has a reduced propensity for cold flow relative to many current silicone pressure sensitive adhesives.
