摘要：
A water-repellent product of inorganic or organic glass excellent in durability performances such as weatherability, water resistance, moisture resistance and abrasion resistance, which is formed of a) a substrate and b) a dense silicon oxide film containing a water-repellent agent containing at least one compound of an organic silicon compound and an organic fluorine compound, the dense silicon oxide film being formed on a surface of the substrate by bringing a silicon dioxide-supersaturated aqueous solution of hydrosilicofluoric acid containing the water-repellent agent into contact with the substrate.
