| abstract |
The present invention relates to a composition for hydrophobization of porous mineral substrates and for producing a dripping off effect at the surface of the substrate, and a method for preparing such a composition, wherein the composition is based on at least one silane oligomer, at least one hydrolysis or condensation catalyst, at least one fluorine-containing polymer, optionally water and/or at least one organic solvent, optionally at least one emulsifier and optionally other auxiliary materials. |
