The invention relates to alkali-stable sol-gel coatings, to a method for producing alkali-stable sol-gel coatings, and to the use thereof. According to the invention, in order to obtain alkali-stable sol-gel coatings, the coating contains the following: a hydrolysable silane of the compounds TEOS, MTEOS or higher-chained alkyl silanes (bifunctional, trifunctional and tetrafunctional silanes), but preferably TEOS, MTEOS or mixtures thereof; and a condensation catalyst based on a) secondary or tertiary bases (e.g. amino, mercaptosilanes) and/or b) Lewis acids as metal alkoxides such as aluminium alkoxides, zirkonium alkoxides, and titanium alkoxides, the ratio (in wt. %) of the hydrolysable silane to the condensation catalyst being between 99:1 and 70:30.

La présente invention concerne des revêtements sol-gel stables aux alcalins, un procédé pour les préparer et leur utilisation. Pour produire les revêtements sol-gel stables aux alcalins, l'invention a pour objet un revêtement qui comprend: un silane hydrolysable des composés TEOS, MTEOS ou alkylsilanes à longue chaîne (silanes di, tri- et tétrafonctionnels), mais de préférence TEOS, MTEOS ou des mélanges de ceux-ci; un catalyseur de condensation à base de a.) bases secondaires ou tertiaires (par ex. amino, mercaptosilanes) et/ou b.) acides de Lewis en tant qu'alcoxydes métalliques tels que les alcoxydes d'aluminium, les alcoxydes de zirconium, les alcoxydes de titane, le rapport (en % en poids) du silane hydrolysable par rapport au catalyseur de condensation, valant entre 99:1 et 70:30.
