  • Mucilages for hydraulic setting compositions
    Patent number: 9284222
    Abstract: The present invention provides an additive blend containing cellulose ether and psyllium suitable for use in dry mix compositions containing a hydraulic binder. The dry mix compositions are particularly useful as a mortar composition, especially for tile adhesives because the compositions improve slip resistance of cement containing tile adhesives, the present invention also provides improved cement containing tile adhesives for larger tiles.
    Type: Grant

    Date of Patent: March 15, 2016
    Assignee: Dow Global Technologies LLC
    Inventors: Rene Kiesewetter, Lars Fengler
  • Redispersible powder composition for dry mortar formulations
    Patent number: 9181131
    Abstract: The present invention relates to a redispersible powder composition for use in the preparation of dry mortar formulations, especially of cementitious bound tile adhesives (CBTA). The invention further relates to a dry mortar formulation comprising said redispersible powder composition. Furthermore, the invention is directed to a method of increasing the open time of a dry mortar formulation without deteriorating the mechanical strength of the cured dry mortar formulation.
