Abstract: A method of making an adhesive article comprises three steps. First, a backing is provided having first and second opposed major surfaces with respective first and second silicone release layers disposed thereon. The second silicone release layer further comprises organic solvent and a compound represented by the formula: R1 represents a monovalent, divalent, or trivalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. Rf represents a perfluorinated group having from 3 to 5 carbon atoms. X1 represents —NH— or a covalent bond. Second, an adhesive layer is disposed onto the first silicone release layer. Third, the adhesive layer is exposed to E-beam radiation within a process chamber containing oxygen to provide a crosslinked adhesive layer. An adhesive article made by the method and the compound are also disclosed.

Abstract: Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.
