Abstract (en)
[origin: CA2611868A1] 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 coatin g contains the following: a hydrolysable silane of the compounds TEOS, MTEOS o r higher-chained alkyl silanes (bifunctional, trifunctional and tetrafunctiona l silanes), but preferably TEOS, MTEOS or mixtures thereof; and a condensation catalyst based on a) secondary or tertiary bases (e.g. amino, mercaptosilane s) 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 70:3 0.
