  • STAIN BLOCKING COMPOSITIONS
    Publication number: 20160130446
    Abstract: An aqueous coating composition for blocking stains and a method of using the coating composition is described. The coating composition includes an aqueous dispersion of a copolymer that is derived from a single stage emulsion polymerization of an ethylenically unsaturated nonionic monomer, greater than 0 and less than 1.5% by weight of an ethylenically unsaturated strong acid monomer or salt thereof, and greater than 1.5% and less than 3% by weight of methacrylic acid.
    Type: Application
    Filed: January 15, 2016
    Publication date: May 12, 2016
    Inventors: Jacob Wildeson, John Kelly, Audrey Cosyns, Harm Wiese

  • Aqueous coating formulation
    Patent number: 8629207
    Abstract: An aqueous coating formulation for tannin-containing substrates can include a substituted C2-C4 polyalkyleneimine. Reacting a C2-C4 polyalkyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic acid derivative can produce the substituted polyalkyleneimine. The carboxylic acid derivative includes at least one C1 to C30 alkyl group or C3 to C30 alkenyl group. Substrates that contain tannin and are coated with this aqueous coating formulation exhibit outstanding resistance with respect to color runs and color strikethrough.

  • AQUEOUS POLYMER DISPERSION AS A BINDING AGENT FOR PLASTERS AND COATING MATERIALS HAVING IMPROVED FIRE BEHAVIOR
    Publication number: 20120121921
    Abstract: Use of an aqueous polymer dispersion comprising at least one polymer (P), obtainable by free radical emulsion polymerization of at least one ethylenically unsaturated monomer (M1) and from 20 to 75% by weight of tert-butyl (meth)acrylate, as a binder in construction chemistry products.
