Abstract
The invention relates to an aqueous solution of modified silicates, wherein the solution is free of organic solvents and is obtained by reacting (a) an initially charge aqueous solution of silicates of the general formula MO·nSiO, wherein M is a cation from the group Li, Na, K, NY, where Y is a hydrogen atom and/or an alkyl or alkenyl radical having 1 to 22 C atoms, and (b) at least one silane of the general formula R—(CH)—Si—(X)where X is independently a CH, OCH, OCH, OCH, OCOCH, H or Cl radical, and R is a saturated or unsaturated, linear or branched or ring-shaped radical having at least one O and/or N atom and at least 2 C atoms, and n is a number between 1 and 3; at temperatures from 5 to 100° C., and wherein the alcohols arising from the conversion are subsequently removed. The aqueous solution of modified silicates is used to hydrophilize surfaces, particularly for high-temperature coatings.
