  • Concrete moldings with a high gloss, their production and use
    Patent number: 7445849
    Abstract: A description is given of a concrete molding which is coated with cement-bound mineral coating composition (cement slurry) and with a transparent varnish, the transparent varnish comprising as binder an aqueous polymer dispersion and also at least one anionic emulsifier containing at least one phosphate and/or phosphonate group. The concrete molding is distinguished by high gloss and can be used in particular as rooftile.
    Type: Grant

    Assignee: Celanese Emulsions GmbH
    Inventors: Gregor Apitz, Helga Machnik, Hans W. Kremer, Stephan Krieger, Klaudia Knell
  • High-solids aqueous dispersions their preparation and use
    Publication number: 20050070653
    Abstract: High-solids aqueous polymer dispersions, their preparation and use A description is given of an aqueous polymer dispersion derived from at least one ethylenically unsaturated monomer and with a solids content of at least 60% by weight, based on the polymer dispersion. The polymer dispersion comprises at least one salt of a phosphorus acid. The preparation takes place by free-radical emulsion polymerization of at least one ethylenically unsaturated monomer in aqueous phase in the presence of at least one emulsifier, at least one initiator and at least one salt of a phosphorus acid. With the process it is possible to prepare aqueous polymer dispersions having a high solids content in combination with a low viscosity, these polymer dispersions being suitable for formulating adhesives.
