Abstract:
1. An article of manufacture comprising (i) at least one glass substrate; (ii) a first coating layer on at least a portion of at least one side of the glass substrate wherein the first coating layer comprises a cured silicone resin composition selected from a hydrosilylation cured silicone resin composition, a condensation cured silicone resin composition, or a free radical cured silicone resin composition; and (iii) a second coating layer on top of at least a portion of the first coating layer wherein the second coating layer comprises a cured silicone resin composition selected from a hydrosilylation cured silicone resin composition, a condensation cured silicone resin composition, or a free radical cured silicone resin composition with the proviso that the composition of the first coating layer is different from the cured silicone resin composition of the second coating layer and wherein the hydrosilylation cured silicone resin composition is a cured product of a silicone composition comprising: (A) a silicone resin having the formula: wherein R 1 is a C 1 to C 10 hydrocarbyl group or a C 1 to C 10 halogen-substituted hydrocarbyl group, both free of aliphatic unsaturation, R 2 is R 1 or an alkenyl group, w has a value of from 0 to 0.8, x has a value of from 0 to 0.6, y has a value of from 0 to 0.99, z has a value of from 0 to 0.35, the sum of y+z is 0.2 to 0.99, and the sum of w+x is 0.01 to 0.80 with the proviso that silicone resin (A) contains at least two silicon-bonded alkenyl groups per molecule; (B) a organohydrogensilane or organohydrogensiloxane containing at least two silicon bonded hydrogen atoms per molecule; (C) a hydrosilylation catalyst selected from complexes of chloroplatinic acid and vinyl containing organosiloxanes, a supported hydrosilylation catalyst comprising a solid support having a platinum group metal on the surface thereof, or a microencapsulated platinum group metal-containing catalyst comprising a platinum group metal encapsulated in a thermoplastic resin; and optionally a hydrosilylation catalyst inhibitor; the condensation cured silicone resin composition is a cured product of a silicone composition comprising: (A wherein R 1 is a C 1 to C 10 hydrocarbyl group or a C 1 to C 10 halogen-substituted hydrocarbyl group, both free of aliphatic unsaturation, R 6 is R 1 , —H, —OH, or a hydrolysable group, and w has a value of from 0 to 0.8, x has a value of from 0 to 0.6, y has a value of from 0 to 0.99, z has a value of from 0 to 0.35, the sum of y+z is 0.2 to 0.99, and the sum of w+x is 0.01 to 0.80, with the proviso that silicone resin (A 1 ) has an average of at least two silicon-bonded hydrogen atoms, or at least two silicon-bonded hydroxy groups, or at least two silicon-bonded hydrolysable groups per molecule; (B (C (A wherein R 1 is a C 1 to C 10 hydrocarbyl group or a C 1 to C 10 halogen-substituted hydrocarbyl group, both free of aliphatic unsaturation, R 9 is R 1 , alkenyl, or alkynyl, w has a value of from 0 to 0.8, x has a value of from 0 to 0.6, y has a value of from 0 to 0.99, z has a value of from 0 to 0.35, the sum of y+z is 0.2 to 0.99, and the sum of w+x is 0.01 to 0.80, with the proviso that silicone resin (A 2 ) has an average of at least two silicon-alkenyl groups or at least two silicon-bonded alkynyl groups per molecule; (B (C
