PROCESS FOR THE SOL-GEL PRODUCTION OF A SUSTAINABLE FUNCTIONAL COATING FOR SUBSTRATES, ESPECIALLY TEXTILE, AND COATING THUS OBTAINED

摘要

The present invention relates to a composition for coating a support comprising: - an aqueous solvent; a polycarboxylic acid; a catalyst for the formation of an anhydrous acid intermediate from the polycarboxylic acid; a sol-gel precursor, all the groups of which are hydrolysable, with functional particles and / or a sol-gel precursor comprising at least one non-hydrolyzable functional group; or a sol-gel precursor comprising at least one non-hydrolyzable functional group, and optionally functional particles, its use for coating a support and the coating thus obtained.
