SUBSTRATE WITH A SURFACE-TREATING COATING LAYER HAVING EXCELLENT FOULING RESISTANCE, WEATHERABILITY, ULTRAVIOLET RESISTANCE AND CHEMICAL RESISTANCE, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A substrate with a surface-treating coating layer is provided to have excellent strength, fouling resistance, weatherability, ultraviolet resistance and chemical resistance.;CONSTITUTION: A substrate with a surface-treating coating layer comprises polysilazane. The substrate has a 3-deminsional surface pattern. The polysilazan contains a silica conversion catalyst of a catalytic amount. A manufacturing method of the substrate with a surface-treating coating layer comprises: a step of forming a polysilazane-coated layer by spreading polysilazane on the surface of the substrate; a step of converting the polysilazane-coated layer to the silica layer by heating the substrate with the polysilazane-coated layer.;COPYRIGHT KIPO 2013
