Release liners coated with a radiation cured silicone release coating

摘要

A process for making a release liner, comprises: applying a composition comprising a radiation curable silicone release agent in an organic solvent to a surface of a substrate wherein the composition further includes volatile silicone compounds; heating the coated substrate, optionally in the presence of high velocity air, under conditions sufficient to remove substantially all of the solvent and essentially all of the volatile silicone compounds; and exposing the coated substrate to radiation under conditions sufficient to substantially cure the radiation curable silicone release agent to form a radiation cured silicone release coating comprising no more than 10 ppm volatile silicone compounds. A release liner having a substrate with opposing surfaces and a radiation cured silicone release coating in an organic solvent coated on a surface thereof. The coating comprises no more than 1.5 micrograms/square centimetre of total extractables and no more than 10 ppm volatile silicone compounds is described.
