    • Coating compositions for producing sol-gel coatings that include: a) one or more alkoxysilyl-containing oxalamides of the general formula (II), where R″ is hydrogen or an organic C1-C10 radical, R′ radicals are organic, optionally oxygen-attached C1-C10 radicals, R is an oxygen-attached radical optionally containing one or more ether groups and having 1 to 30 carbon atoms and n is an integer between 0 and 2, b) optionally further crosslinkers, c) one or more catalysts and d) water. The sol-gel coatings are produced by a method that includes combining a silica sol and one or more alkoxysilyl-containing oxalamides. The sol-gel coatings obtained from the above-described coating compositions can be used to coat substrates.
    • 用于生产溶胶 - 凝胶涂层的涂料组合物,其包括:a)一种或多种通式(II)的含烷氧基甲硅烷基的草酰胺,其中R“为氢或有机C 1 -C 3 R 10自由基是有机的,任选地与氧连接的C 1 -C 10基团,R是含氧的基团,任选地含有一个或多个 更多的醚基团并且具有1至30个碳原子,n是0和2之间的整数,b)任选地进一步的交联剂,c)一种或多种催化剂和d)水。 溶胶 - 凝胶涂层通过包括将硅溶胶与一种或多种含有烷氧基甲硅烷基的草酰胺结合的方法制备。 由上述涂料组合物获得的溶胶 - 凝胶涂层可用于涂覆基材。
