Abstract

This invention provides a single phase silicone acrylate formulation that resists phase separation and includes (A) at least one of a silicone, an acrylate, and combinations thereof. The single phase silicone acrylate formulation also includes (B) a silicone acrylate hybrid compatibilizing agent including silicone functionality and (meth)acrylate functionality and that is the reaction product of a silicon-containing pressure sensitive adhesive composition, a (meth)acrylate, and an initiator. A method of minimizing phase separation of the single phase silicone acrylate formulation includes the step of combining (A) and (B) to form the single phase silicone acrylate formulation.
