Abstract
A method of strengthening glass using a mixture of a silane and a resin, the mixture being applied to the glass surface as an aqueous emulsion which is then cured. The silane is a reaction product of a silane coupling agent, which contains an epoxy group, with an unsaturated carboxylic acid, and the resin is a resin having at least two polymerisable unsaturated groups in the molecule. Preferably the silane and the resin have unsaturated reactive groups of matched reactivity. Advantageously the mixture contains about 20 parts of the silane per hundred parts of the resin. In another embodiment a silane coupling agent is dissolved in a polymerisable resin, the mixture of silane and resin is emulsified in water, the emulsion being applied as a coating, which is then cured.
