Abstract: A curable composition is disclosed. The curable composition comprises (I) an epoxide-functional silicone-acrylate polymer, (II) an aminosiloxane, and (III) a conductive filler. The epoxide-functional silicone-acrylate polymer comprises acrylate-derived monomeric units comprising siloxane moieties, epoxide-functional moieties, and optionally, hydrocarbyl moieties, and the aminosiloxane comprises an average of at least two amine functional groups per molecule. Methods of preparing the curable composition, and a cured product thereof, are also disclosed. A method of forming a composite article comprising a conductive layer with the curable composition is disclosed is also disclosed. The method comprises disposing the curable composition on a substrate, and curing the curable composition to give a conductive layer on the substrate, thereby forming the composite article.

Abstract: A curable composition is disclosed. The curable composition comprises (I) an epoxide-functional silicone-acrylate polymer and (II) an aminosiloxane. The epoxide-functional silicone-acrylate polymer comprises acrylate-derived monomeric units comprising siloxane moieties, epoxide-functional moieties, and optionally, hydrocarbyl moieties, and the aminosiloxane comprises an average of at least two amine functional groups per molecule. A method of preparing the curable composition is also disclosed, and includes reacting (A) an acryloxy-functional organosilicon component, (B) an epoxy-functional acrylate component, and optionally (C) an acrylate component, to give the epoxide-functional silicone-acrylate polymer (I), and combining the epoxide-functional silicone-acrylate polymer (I) with the aminosiloxane (II). An aminosiloxane-silicone-acrylate copolymer prepared with the composition, a cured product comprising the same, and methods of preparing the same, are also disclosed.
