摘要:
A coated plastic molded article composed of a plastic article on the surface of which laminated are (a) a first layer composed of a cured composition containing a partially hydrolyzed product of at least one silicon compound, (b) a second layer composed of a cured, partially hydrolyzed product of another silicon compound, and (c) a third layer composed of the silicon dioxide from an aqueous hydrosilicofluoric acid solution supersaturated with silicon dioxide, by the order of (a), (b) and (c) ; and a process for preparing the coated plastic molded articles.
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.
