Abstract
A dispersion, comprising 0.1 to 25% by weight hydrophobized silica, 8 to 90 wt % of at least one alcohol selected from the group consisting of ethanol, 1-propanol and 2-propanol, 7 to 89 wt % of water, 0 to 30% by weight solvent immiscible with water, and 0.04 to 5 wt % of at least one carboxyvinyl polymer present in neutralized form, can be applied to a surface using a non-drip application method and, by modifying the surface with hydrophobized silica, imparts water-repelling and self-cleaning properties to the surface.
