The present invention relates to a method of strengthening brittle oxide pieces such as glass pieces with a siloxane-acrylate coating system that has superior weatherability, particularly hydrolytic stability. The coating system comprises a combination of a silane solution and a radiation-curable acrylate solution. The mixture is applied to a clean, brittle oxide surface. The silane solution comprises one or more silanes in a non-aqueous solvent and the radiation-curable acrylate solution comprises one or more acrylate or methacrylate monomers, acrylate or methacrylate oligomers, and initiators, such as photoinitiators.
La présente invention concerne un procédé de renforcement de pièces d'oxydes cassants tels que des pièces en verre dotées d'un système de siloxane-acrylate une résistance aux intempéries supérieure, notamment une sabilité hydrolytique. Le système de revêtement comprend une association d'une solution de silane et une solution d'acrylate durcissable par exposition à un rayonnement. Ce mélange est appliqué sur une surface d'oxyde cassant propre. Cette solution de silane comprend au moins un silane dans un solvant non aqueux et la solution d'acrylate durcissable par exposition à un rayonnement comprend au moins un monomère acrylate ou méthacrylate, un oligomère acrylate ou méthacrylate et des initiateurs, tels que des photoinitiateurs.
