ABSTRACT:
The instant invention pertains to a hot-melt pressure sensitive adhesive composition wherein the composition is comprised of a silicone pressure sensitive adhesive selected from the group consisting of a mixture of (i) a silicone resin and (ii) a silicone fluid and a condensed product of (i) and (ii); the silicone pressure sensitive adhesive exhibiting tackiness and adhesiveness; the silicone pressure sensitive adhesive being blended with (iii) from about 1 to 20 weight percent, based on the total weight of (i) and (ii), of a siloxylated polyether wax. The instant invention also encompasses method of using the composition, methods of making hot-melt silicone pressure sensitive adhesive-coated substrates, and devices made using the composition.
