Manufacture of uv shielding glass and window glass for automobile and window glass for building

PURPOSE:To provide a method for manufacturing an UV shielding glass by which the UV shielding glass excellent in resistances to scuffing and wear and suitable for window glass for automobile and building is obtd. CONSTITUTION:Fine zinc oxide particles having <=0.1mum particle diameter are mixed into an organopolysiloxane solution at the ratio of SiO2/ZnO of 0.25-0.67 (weight ratio). Subsequently the solution obtained by dispersing the fine zinc oxide particles is applied on a sheet glass at the film thickness of 0.2-1.5mum in a dry state. Later the sheet glass is fired at 580-700 deg.C to produce the UV shielding glass. The obtained UV shielding glass is highly suitable for the window glass for automobile and the window glass for building.
