Abstract
A method of making a pressure-sensitive adhesive assembly, the method including coating a pressure-sensitive adhesive composition that includes a silicone polymer on a first major surface of a first release liner to form a first layer, coating a composition on the first layer to form a second layer, the composition of the second layer including an elastomer, at least one of the pressure-sensitive adhesive composition of the first layer and the composition of the second layer being in an uncured state during the coating of the second layer, and curing at least one of the first layer and the second layer, the first pressure-sensitive adhesive composition 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.
