CURABLE SILICONE-(METH)ACRYLATE COMPOSITION AND METHODS FOR ITS PREPARATION AND USE
A curable silicone-(meth)acrylate pressure sensitive composition is curable via hydrosilylation reaction to form a silicone-(meth)acrylate pressure sensitive adhesive with an initial adhesion. When the silicone-(meth)acrylate pressure sensitive adhesive is exposed to actinic radiation, the resulting silicone-(meth)acrylate adhesive has a subsequent adhesion, which is higher than the initial adhesion.
