  • Polyamine additive
    Patent number: 11820845
    Abstract: Polyamine additives are disclosed that are useful to provide early water resistant to drying anionically colloidally stabilized polymer dispersions in aqueous media. The polyamines are polymerization products from ethylenically unsaturated monomers with pendant tertiary amine groups with ethylenically unsaturated monomers with pendant poly(alkylene oxide) chains of 88 to 1200 g/mole molecular weight.
    Type: Grant
    Filed: September 25, 2019
    Date of Patent: November 21, 2023
    Assignee: LUBRIZOL ADVANCED MATERIALS, INC
    Inventors: Shui-Jen R. Hsu, Dominic Cremona, Darlene D. Rota, Adlai J. Perry, Keith Rawlins, Stephan A. Horvath
  • Fast Drying Waterborne Coatings
    Publication number: 20220033638
    Abstract: Coating and ink formulations are disclosed that are comprised of an anionically colloidally stabilized copolymer dispersion, a polyamine additive that can react with anionic groups, and a volatile base that can help shift the pH of the copolymer dispersion early in the drying process of films or coatings from the copolymer dispersion. The formulations are used in construction and roof coatings.

  • Aqueous copolymer coating compositions for industrial and construction applications
    Patent number: 11130869
    Abstract: Copolymer dispersions containing polyamide segments in aqueous media form binders for coatings for various industrial and construction materials. The copolymers have a high percentage of amide linkages. The copolymers are linked into higher molecular weight species by reactions with polyisocyanates (which forms urea linkages if the other reactant is an amine or a urethane linkage if the other reactant is a hydroxyl group).
