Abstract

The invention relates to an aqueous composition based on tris-silylated amino-functional silicon compounds, which is substantially free of organic solvents and which substantially does not release any alcohol even during the cross-linking process, and to method for the production thereof, and to the use thereof, for example for the hydrophobization of metal, glass or mineral surfaces, such as concrete and bricks, as adhesion promoter or for rock consolidation, among other things.
