COMPOSITION FOR TREATING GLASS-CERAMIC OR GLASS TO IMPROVE MECHANICAL STRENGTH THROUGH CURING OF SURFACE DEFECTS, TREATMENT METHODS

摘要

The invention concerns a composition for treating the surface of glass-ceramic in particular in plate form, flat or hollow glass, or in the form of fibers, suitable for application in thin layer on said glass-ceramic or said glass. It comprises, in aqueous medium, the following constituents (A) and (B): (A) at least one compound comprising at least one function f_(A); and (B) at least one compound comprising at least one function f_(B) capable of reacting with the function(s) f_(A) of constituent (A) inside the thin layer applied on the glass-ceramic or the glass so as to transform the latter through polycondensation and/or polymerization into a solid layer, at least one of the compounds comprised in the definition of (A) and (B) containing at least one R-O- function bound to a silicon atom, R representing an alkyl radical, and at least part of the compounds containing at least one R-O- function bound to a silicon atom that may be in hydrolyzed form resulting from prehydrolysis or spontaneous hydrolysis occurring upon contact of the compound(s) with the aqueous medium.
