  • Patent number: 12134692
    Abstract: A crosslinkable polymer powder compositions redispersible in water includes one or more vinyl ester polymers, one or more compounds bearing epoxide groups and optionally one or more curing agents which crosslink with the compounds bearing epoxide groups. The vinyl ester polymers do not comprise any epoxide-functional monomer units. The crosslinkable polymer powder compositions redispersible in water includes ?51% by weight, based on the total weight of the vinyl ester polymers, of one or more compounds bearing epoxide groups.
    Type: Grant
    Filed: February 26, 2019
    Date of Patent: November 5, 2024
    Assignee: Wacker Chemie AG
    Inventors: Timo Melchin, Ulf Dietrich, Heimo Wölfle

  • Patent number: 11220783
    Abstract: The object of the invention is the use of an aqueous dispersion of a vinylacetate-ethylene-copolymer and of at least one polyethylene imine as a binder in a carpet coating composition for the production of carpets.

  • Patent number: 10480122
    Abstract: The invention relates to the use of mixtures that contain an aqueous dispersion of a vinyl acetate polymer and an aqueous dispersion of a vinyl acetate-ethylene copolymer for carpet coating compositions, and corresponding carpet coating compositions, as well as carpets which are coated with such carpet coating compositions.

  • Patent number: 10457827
    Abstract: The invention relates to an aqueous vinyl acetate-ethylene-copolymer dispersion for carpet coating compositions, which is obtained by means of radical-initiated emulsion polymerization, in an aqueous medium, of vinyl acetate and ethylene and optionally additional ethylenically unsaturated comonomers, characterized in that, for stabilization of the dispersion, 5 to 10 wt %, based on the total weight of the comonomers, of one or a plurality of partially saponified and low-molecular polyvinyl alcohols having a hydrolysis degree of 80 to 95 mol % and a Höppler viscosity, in 4% aqueous solution, of 1 to 5 mPas (method according to Höppler at 20° C., DIN 53015) are contained.

  • Patent number: 10227726
    Abstract: The use of redispersible polymer powders containing no organic emulsifier for a binder in the production of carpeting is surprisingly superior to use of the same polymers in the form of an aqueous dispersion. Tuft removal force in particular, is improved. The compositions contain no thickener, or a reduced level of thickener.
