Glass scratch surface coating composition, glass coated with glass scratching surface with this composition, and method of coating scratched surface of glass using the composition

摘要

PROBLEM TO BE SOLVED: To provide a scratched glass surface coverage composition capable of preventing the deterioration of edge plane strength and, as a result, of inhibiting cleavages originating from microcracks.SOLUTION: The composition of the present invention includes, within a solute, at least 50 wt.% of a modified amino group-containing silane and/or isocyanurate silane. It is desirable for the modified amino group-containing silane to be a reaction product of (A) a substituted or unsubstituted amino group-containing silane and (B) an epoxy group-containing compound, isocyanate group-containing compound, or (meth)acryloyl group-containing compound, and it is more desirable for (A) the amino group-containing silane and (B) the epoxy group-containing compound, etc., to be reacted at a weight ratio of 100 : 30-400. The problem can be solved by coating and drying the composition on a scratched surface of a glass so as to form thereon a cured film.
