Ionic organosilicon compounds are provided comprising ethylene glycol functionality and aqueous compositions comprising such ionic organosilicon compounds; wherein the aqueous compositions are suitable for imparting water repellency to a wide variety of surfaces. The compositions of the present invention are prepared by dissolving ionic organosilicon compounds in water. Surprisingly, it has been found that the water soluble ionic organosilicon compounds, which have an ionic group, a hydrophobic group and at least one alkoxy group on silicon, of the present invention provide treated surfaces with excellent hydrophobicity.
提供含有乙二醇功能的离子有机硅化合物和含有这种离子有机硅化合物的水性组合物;其中,这种水性组合物适用于赋予各种表面防水性。本发明的组合物是通过在水中溶解离子有机硅化合物制备的。令人惊讶的是,发现本发明的水溶性离子有机硅化合物,在硅上具有离子基团、疏水基团和至少一个烷氧基团,能够为处理过的表面提供出色的疏水性。
