ABSTRACT:
An ultraviolet radiation curable silica coating composition containing (a) acrylic monomers, (b) functionalized colloidal silica, (c) acrylated urethanes, (d) an ultraviolet radiation absorber, and (e) a photoinitiator. The coating composition once applied to and cured on a thermoplastic substrate provides a coating which exhibits improved flexibility and weathering. The coatings are useful for providing abrasion resistance and weatherability to thermoplastic, for example polycarbonate, substrates.
