  • Patent number: 7727595
    Abstract: A radiation or thermal curable coating composition contains a cycloaliphatic epoxide resin, a carbinol functional silicone resin or an anhydride functional silicone resin, and a thermal or photoactivated acid catalyst. An organic polyol may also be included in the composition as an optional component. The composition is useful as a radiation curable coating, as an adhesive, a photodefinable coating, or as a thermal cure coating. The cycloaliphatic epoxide resin adds toughness and adhesion to the composition, whereas either of the carbinol functional silicone resin or the anhydride functional silicone resin provides the composition with water resistance, weatherability, thermal stability, and flexibility.
