Abstract:
A multi-layer assembly that includes a release liner, a first layer disposed on the release liner, the first layer including a pressure-sensitive adhesive composition that includes a silicone polymer that includes silicone polyurea block copolymers, polydiorganosiloxane polymers, or combinations thereof, a second layer disposed on the first layer, the second layer including a composition that includes an elastomer, the composition of the second layer being different from the pressure-sensitive adhesive composition of the first layer, the first layer of the multi-layer assembly exhibiting a release force to the release liner of no greater than 100 gram per 0.5 inch width after the multi-layer assembly has been stored for 46 days at 120° F.
