<p>The present invention relates to an aqueous dispersion base, to a coating produced therewith, and to methods for producing a vapor barrier or an intermediate layer. The aqueous, polymer-based dispersion base for cementitious and/or other substrates is characterized in that the aqueous dispersion base contains the following substances in an aqueous dispersion: a) â¿¥ 23 wt % of silanized styrol/acrylate copolymer and b) â¿¥ 7.5 wt % of vinylidene chloride/acrylate copolymer and c) â¿¥ 0.5 wt % of a mixture of styrol/butadiene copolymer and paraffin wax and d) â¿¥ 0.5 wt % of additives, wherein the percentage specifications are related to the mass of the ready-to-use dispersion base.</p> |
