摘要:
A two-pack type water repellant for glass surfaces which, when applied to a surface of a glass in, e.g., a motor vehicle, can give a water-repellent coating film capable of retaining excellent water repellency over long and which has excellent storage stability. The water repellant is of the two-pack type in which the two liquids are mixed together just before application to a glass surface. It is constituted of liquid A containing as an active ingredient a fluorosilane compound having a hydrolyzable functional group and liquid B containing as an active ingredient a catalyst ingredient exerting a catalytic action on the fluorosilane compound.

摘要:
A stain inhibitor, which acts to neutralise the alkali leached to the surface of a sheet of glass in the presence of water, is disclosed. The stain inhibitor comprises a compound that reacts with the water to produce an acid. The acid acts to neutralise the alkali leached to the surface of the glass. Preferably, the compound hydrolyses to produce the acid, and is an ester.
