SILICONE COATING MATERIAL AND TRANSPARENT SUBSTRATE HAVING HEAT-SHIELDING STRUCTURE

摘要

An object of the present invention is to provide a silicone coating material which, when applied to a transparent substrate such as glass, can provide a coating film which is excellent in surface uniformity and adhesion, has high hardness, and has characteristics capable of sufficiently shielding heat rays such as near-infrared rays. The silicone coating material comprises a silane solution comprising an alkoxysilane hydrolysate and a dispersion of indium tin oxide (ITO) (ITO dispersion), the solution and the dispersion being mixed for service. ITO particles in the ITO dispersion are silane-treated. The silane treatment agent (silane coupling agent) in the silane treatment is preferably an ω-glycidoxyalkylalkoxysilane represented by general formula (I):;wherein R1 and R4 each represent H or CH3; R2 represents an alkylene group having 1 to 4 carbon atoms; R3 represents an alkyl group having 1 to 4 carbon atoms; and n=0 or 1.
