    摘要: A water-repellent glass having a durable and abrasion-resistant silica layer is prepared by a process containing the following steps: (a) preparing a silica solution by subjecting a metal alkoxide-based silane compound to a two step aging process wherein the two step aging process is proceeded either by conducting a first aging step under a basic condition and a second aging step under an acidic condition or vice versa, (b) applying the resulting silica composition onto the surface of a glass substrate, (c) subjecting the glass substrate coated with the silica composition to a thermal treatment, and (d) coating the resulting coarse silica layer with a water-repellent layer.

    摘要: A water-repellent glass comprising a uniform and optically transparent silica film with excellent durability and hardness is prepared by a process which comprises: (a) preparing a colloidal silica suspension by hydrolyzing and polycondensing an alkoxysilane in an organic solvent under a basic condition in the presence of water, and then treating the colloidal silica suspension under an acidic condition, to obtain a silica dispersion containing cross-linked spherical silica particles and linear polysiloxane, (b) combining the silica dispersion with a mixed solvent composed of acetic acid and an alcohol to obtain a coating composition, (c) applying the coating composition on the surface of a glass substrate to form a silica layer therefrom, (d) heat treating the silica layer to provide a silica film on the glass substrate, and (e) applying a water-repellent agent on the silica film to provide the water-repellent glass.

    摘要: A glass substrate is provided with a durable and abrasion-resistant water-repellent surface, by coating a surface of the substrate with a silica solution which has been subjected to a two-step aging process, respectively in the presence of basic and acidic catalysts, which is then thermally treated to provide a coarse-surfaced silica layer including fine crystalline silica particles, which is then coated with a water-repellent layer made of fluoroalkylsilane.
