  • Publication number: 20140093727
    Abstract: A method including: a. coating at least a portion of at least one major surface of a substrate with a polymerizable composition to obtain a coated surface; b. initiating polymerization of the polymerizable composition by scanning a first electron-beam focused on the coated surface across at least a portion of the coated surface, thereby irradiating the coated surface at a frequency selected to achieve an exposure duration of greater than 0 and no greater than 10 microseconds, and a dark time between each exposure duration of at least one millisecond, thereby producing an at least partially polymerized composition. A pressure sensitive adhesive article and a cross-linked silicone release liner made according to the method are also disclosed.
