  • Publication number: 20240010885
    Abstract: Disclosed is an aqueous dispersion parquet adhesive based on at least one dissolved polyvinyl alcohol, at least one dispersed, vinyl acetate-containing polymer, and at least one dispersed, acrylate-containing polymer. The dispersion parquet adhesive has low density, excellent processing properties, and advantageous mechanical properties. The dispersion parquet adhesive according to the invention has an exceptionally high weight ratio of polymeric binder to water and a defined weight ratio of dissolved polymeric binder to dispersed polymeric binder. Also disclosed is a method of producing the parquet adhesive.

  • Patent number: 8680193
    Abstract: 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.

  • Publication number: 20060069194
    Abstract: Described is a low-emission adhesive, whose polymers are dissolved in a mixture of acetone and ethanol. The adhesive is characterized by very low emissions of solvents, with otherwise equally good properties compared to standard solvent-synthetic resin based adhesives. In particular with respect to viscosity and spreadability, surface tension, depth of penetration, wettability, simplicity and speed of processing, as well as adhesion, gluing strength and adhesive spectrum, the adhesive of the invention is equal to other adhesives based on solvents and thus superior to dispersion-adhesives that are based on aqueous solutions. Due to its low solvent emissions and absence of chlorinated solvents, the present adhesive is suitable for applications for which only dispersion-adhesives that are based on aqueous dispersions were reserved until now. This is true in particular for applications in enclosed spaces. The adhesive is very suitable for gluing of wooden floors in internal construction work.
