COMPOSITION FOR BUILDING PROTECTION APPLICATIONS BASED ON ALKYLALKOXY-SILOXANES HAVING IMPROVED WATER REPELLENCY PROPERTIES

摘要

The present invention relates to a composition for imparting water repellency to porous mineral substrates and for producing a water repellency effect on the surface of the substrate and to a process for the preparation of such a composition, said composition being based onat 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 andoptionally further auxiliaries.
