Multi-layer assembly, multi-layer stretch releasing pressure-sensitive adhesive assembly, and methods of making and using the same
First Claim
1. A multi-layer assembly comprising:
- a release liner comprisinga first major surface,a second major surface,a first release agent on the first major surface of the release liner, the first release agent comprising the reaction product of a fluorosilicone polymer comprising at least about 35% fluorine substitution and an organohydrogenpolysiloxane crosslinking agent, anda second release agent on the second major surface of the release liner;
a first layer comprising a pressure-sensitive adhesive composition disposed upon and in contact with the first release agent on the first major surface of the release liner, the pressure-sensitive adhesive composition comprising silicone polyurea block copolymer; and
a second layer comprising a pressure-sensitive adhesive composition comprising an elastomer disposed upon and in contact with the first layer, the composition of the pressure-sensitive adhesive composition of the second layer being different from the composition of 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 grams per 0.5 inch width after the multi-layer assembly has been stored for 46 days at 120°

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.
