EMULSIONS OF ORGANOSILICON COMPOUNDS FOR IMPARTING WATER REPELLENCY TO BUILDING MATERIALS

摘要

Aqueous emulsions contain the components (A) organosilicon compounds which are selected from (A1) C1-C20-hydrocarbon-C1-C6-alkoxysilanes and (A2) branched organopolysiloxanes containing C1-C6-alkoxy groups, (B) organosilicon compounds which are selected from (B1) C1-C6-alkoxysilanes containing aminoalkyl groups and (B2) branched organosiloxanes containing aminoalkyl groups and (C) an emulsifier. The aqueous emulsions are suitable for imparting water repellency to porous mineral building materials and building coatings and to wood.
