RADIATION CURABLE COMPOSITION, AND METHOD FOR PREPARING A HYBRID SOL-GEL LAYER ON A SURFACE OF A SUBSTRATE USING SAID COMPOSITION.

摘要

Radiation curable composition for preparing a hybrid sol-gel layer on a surface of a substrate, wherein said composition comprises at least one radiation material capable of being polymerized and/or crosslinked by a cationic polymerization reaction upon exposure to a radiation; a combination of at least one organofunctional silane; and of at least one other silane selected from among the group consisting of poly(alkoxy siloxane), 3-glycidyloxypropyltrimethoxysilane (GPTMS), 2-(3,4- epoxycyclohexylethyltrimethoxysilane (TRIMO); and at least one cationic photoinitiator. Method for preparing a hybrid sol-gel layer on a surface of a substrate using said composition and hybrid sol-gel layer so prepared. Substrate comprising at least one surface coated with said hybrid sol-gel layer.
