A film is described comprising a (meth)acrylic polymer and polyvinyl acetal polymer composition. A layer of an adhesive composition is disposed proximate the film. The adhesive composition has a tensile elastic modulus of less than 1 MPa at 25 C. and 1 hertz.
Low Adhesion Backsize For Silicone Adhesive Articles And Methods
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.
