ABSTRACT:
The present invention includes a novel polyol prepolmer including either an aliphatic amine, cycloaliphatic amine, aromatic amine or a mixture of these with an epoxy functional silicone to produce the novel polyol prepolymer chain extender. In one aspect of the invention, the novel polyol prepolymer chain extender is reacted with an epoxy resin to produce a novel silicone modified epoxy resin having improved adhesion, chemical resistance, UV stability, and decreased shrinkage properties. In another aspect of the invention, the novel polyol prepolymer chain extender is reacted with an acrylic monomer to produce a novel silicone modified acrylic resin having improved adhesion, chemical resistance, UV stability, increased functionality, and decreased shrinkage properties. The present invention also provides for a novel solid surface material composition.
