Estimating the term…
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. .
An aqueous emulsion containing organosilicon compounds useful for imparting water repellancy which contains an emulsifier, wherein said organosilicon compounds consist essentially of
A process for imparting water repellancy to porous mineral building materials and building coatings and to wood, in which said building materials, building coatings, and wood are treated with an emulsion comprising
An aqueous emulsion which contains the components
An aqueous emulsion of organosilicon compounds suitable for increasing water repellancy of building materials, said emulsion comprising one or more silane component(s) and an organopolysiloxane component,
