ABSTRACT:
The invention provides a method for making a curable epoxysilicone composition through the hydrosilation reaction between an ethylenically unsaturated epoxide and an SiH-containing silicone to produce an epoxysilicone product, and catalyzed by a quaternary ammonium, phosphonium or arsonium hexahaloplatinate which does not promote the oxirane ring-opening reaction of either the ethylenically unsaturated epoxide starting material or the epoxysilicone product. The invention also provides for a curable epoxysilicone composition made by the above method.
