PROCESSING COMPOSITION OF A VITROCERAMIC FOR IMPROVING THE MECHANICAL RESISTANCE BY HEALING SURFACE DEFECTS, CORRESPONDING PROCESSING METHODS AND TREATED VITROCERAMIC PRODUCTS OBTAINED

摘要

This composition for treating the surface of a glass ceramic, in particular in a plate, a flat or hollow glass, or in the form of fibers, is suitable for being applied in a thin layer to 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 component (A) within the thin layer applied to the glass-ceramic or glass in order to transform the latter by polycondensation and / or polymerization in a solid layer, at least one of the compounds falling within the definition of (A) and of (B) comprising at least one RO- function attached to a silicon atom, R representing an alkyl residue, and at least part of the compounds comprising at least one RO- function attached to a silicon atom which may be in a hydrolyzed form resulting from a prehydrolysis or from a spontaneous hydrolysis which takes place during contact with the compound (s) with the aqueous medium.
