Abstract
Abstract The present invention relates to a silicone coating composition which, when cured on a solid substrate either by ultraviolet or electron beam radiation, provides a transparent abrasion resistant coating firmly adhered thereon. The silicon coating is prepared by reacting at least one multifunctional acrylate monomer with an amino-organofunctional silane, mixing the modified silane with at least one acrylic monomer and thereafter adding colloidal silica.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
150 words
A method of coating a surface on a substrate with an abrasion-resistant coating comprising the steps of: (1) formulating a coating composition by reacting the following components in a solution of a polar solvent: at least one multifunctional acrylic monomer; an amino-organofunctional silane of the formula X.sub.a Si{Q(NHQ').sub.b NZH}.sub.4-a wherein X is selected form alkoxy groups having 1 to 6 carbon atoms; Q and Q' are the same or different divalent hydrocarbon groups; Z is hydrogen or a monovalent hydrocarbon group; a is an integer from 1 to 3; and b is an integer from 0 to 6; for a time and at a temperature sufficient to form a Michael adduct therefrom; (2) adding an acid to the above-resulting solution; and thereafter (3) adding colloidal silica to the above-resulting solution; (4) applying the resulting coating composition to the surface of said substrate; and (5) curing the coating composition with radiation.
Claim 2
Independent Claim
150 words
A method of coating a surface on a substrate with an abrasion-resistant coating comprising the steps of: (1) formulating a coating composition by reacting the following components in a solution of a polar solvent: at least one multifunctional acrylic monomer; an amino-organofunctional silane of the formula X.sub.a Si{Q(NHQ').sub.b NZH}.sub.4-a wherein X is selected form alkoxy groups having 1 to 6 carbon atoms; Q and Q' are the same or different divalent hydrocarbon groups; Z is hydrogen or a monovalent hydrocarbon group; a is an integer from 1 to 3; and b is an integer from 0 to 6; for a time and at a temperature sufficient to form a Michael adduct therefrom; (2) adding an acid to the above-resulting solution; and thereafter (3) adding colloidal silica to the above-resulting solution; (4) applying the resulting coating composition to the surface of said substrate; and (5) curing the coating composition with radiation.
