| 摘要 |
The present invention relates to an aqueous dispersion primer, a coating produced therewith and a method for the production of a vapour barrier or of an intermediate layer. The aqueous dispersion primer based on a polymer for cement and/or other subfloors is characterised in that it contains in an aqueous dispersion the following materials: a) ≧23% by weight of silanised styrene-acrylate copolymer and b) ≧7.5% by weight of vinylidene chloride-acrylate copolymer and c) ≧0.5% by weight of styrene-butadiene copolymer-paraffin wax mixture and d) ≧0.5% by weight of additives, the percentage data relating to the mass of the dispersion primer, ready for handling. |
