Cross-linked gel and pressure sensitive adhesive blend, and skin-attachable products using the same

摘要

A pressure sensitive adhesive composition comprising a compatible blend of (1) a gel preferably comprising a copolymer of an organosiloxane and a siloxane having a plurality of reactive functionalities reacted with a cross-liking agent; and (2) a pressure sensitive adhesive that preferably is essentially non-reactive with the reactive functionalities of said copolymer gel or the copolymer cross-liking agent of said gel, wherein the essentially non-reactive pressure sensitive adhesive is a silicone pressure sensitive adhesive and has a higher adhesive strength than said gel and is blended with said copolymer during cross-linking of said copolymer to form said gel.
