Abstract

The present invention provides a storage stable silicon-containing powder composition suitable for use in dry mix compositions containing cement and filler suitable as cement-based tile adhesives, the powder composition comprising (i) a water redispersible polymer powder (RDP); and, (ii) a granular composition of (a) a silicate carrier, (b) a polydiorganosiloxane, (c) a hydrolysable silane containing a Cto Calkyl group, or an oligomer thereof, and (d) a polymer encapsulant for the hydrolysable silane and the polydiorganosiloxane, wherein the weight ratio of the total RDP to the total weight of granular composition ranges from 90:10 to 98:2. The present invention provides methods of using dry mixes as cement-based tile adhesives wherein the powder composition enables good open time and excellent tensile adhesion, especially after heat aging.
