摘要：The invention relates to an aqueous dispersion and dispersion powder
composition for highly flexible, waterproof, hydraulically binding tile adhesives having anextended open time, and containing an emulsion polymer (A) having a glass transitiontemperature (Tg) of approximately 10° C. to 80° C., and an emulsion polymer (B) having aglass transition temperature (Tg) of approximately -60° C. to +20° C. The difference ofthe glass transition temperatures (Tg) of the emulsion polymers (A and B) is at leastapproximately 5° C. The proportion of vinyl acetate monomer units is 0 to 70 mol-% andthe minimum film forming temperature according to DIN 53787 of the 50% aqueousdispersion composition is approximately 15° C. or less, and the monomers, stabilizationsystems and optionally the additional additives of the dispersion and/or dispersionpowder composition are selected such that a good cement compatibility is guaranteed.Due to the inventive dispersion and dispersion powder composition, tile adhesive can beproduced in an economical manner which meets the requirements of C2S2- and C2ES2-norm according to EN12004.
