Abstract
Hydraulically setting compositions containing mineral binders exhibit improved adhesion when polymer powders produced by drying a silica sol and a redispersible polymer powder emulsion are added.
Claims6
A method for producing dry building material formulations, comprising mixing one or more hydraulically setting binders, one or more fillers, one or more polymers in the form of water-redispersible polymer powders, and optionally one or more additives, wherein the polymer powders are prepared by drying aqueous dispersions comprising one or more silica sols and one or more polymers of ethylenically unsaturated monomers.
