Abstract
An epoxy-curable silicone release coating composition and methods for its preparation and use are provided. The composition contains an inhibited Lewis acid catalyst. Releasing the Lewis acid catalyst from the inhibitor allows the Lewis acid to catalyze cure of the epoxy-groups. The composition can be coated on various substrates and cured to form a release liner.
