Document Type and Number:
WIPO Patent Application WO/2006/092941
Kind Code:
A1
Abstract:
Provided are a method for manufacturing a water-using home facility or equipment exhibiting good hydrophilic property, surface hardness and appearance, and the above water-using home facility or equipment. A water-using home facility or equipment which has a coating film comprising silicic acid on the surface of a substrate and, formed on the coating film comprising silicic acid, a coating film comprising Si in an amount of 44 to 97 mass % in terms of SiO2, Li in an amount of 0.2 to 17 mass % in terms of Li2O and Na in an amount of 2.4 to 49 mass % in terms of Na2O; and a method for manufacturing the above water-using home facility or equipment which comprises a surface treatment step of treating at least the surface of the substrate to be contacted with water or a steam atmosphere with the coating agent comprising silicic acid, to thereby form a surface treatment layer, and an applying step of applying an aqueous solution containing Si in an amount of 1 to 20 mass % in terms of SiO2, Li in an amount of 0.05 to 0.3 mass % in terms of Li2O and Na in an amount of 0.5 to 1 mass % in terms of Na2O, to thereby form an applied layer.
