机译:硅酮胶制品和方法的低附着力背胶

摘要

Low adhesion backsize (LAB) compositions including a silicone macromonomer co polymerized with a crystalline (meth)acrylate monomer to form a copolymer. The copolymer exhibits a glass transition temperature of from about 15° C. to about 55° C., and a crystalline melt transition of from about 25° C. to about 80° C. Articles including the LAB composition applied to a first major surface of a substrate. In some exemplary embodiments, the article is an adhesive article. In certain exemplary embodiments, the article is a pressure-sensitive adhesive (PSA) article. In some particular embodiments, the PSA article includes a silicone adhesive applied to a second major surface of the substrate opposite the LAB composition. Methods of making and using the LAB and the articles are also disclosed.
