Patent ID: 8198389

Claim:
A process of making a mold release coating compound comprising the steps of (A) combining and reacting hydride terminated poly(dimethylsiloxane-co-methylhydrosiloxane), 4-vinyl-1-cyclohexene diepoxide and a rhodium catalyst in a reaction vessel to yield a cycloaliphatic epoxide functionalized polydimethylsiloxane compound; (B) mixing the cycloaliphatic epoxide functionalized polydimethylsiloxane compound with a photoinitiator and a photosensitizer to yield a mixture; (C) coating the mixture on a surface to provide release characteristics; and (D) curing the coating with visible light, wherein the cycloaliphatic epoxide functionalized polydimethylsiloxane compound is functionalized with at least two cycloaliphatic epoxides with at least one cycloaliphatic epoxide being located on a terminal silicon atom and at least one cycloaliphatic epoxide being located on an internal silicon atom.
