  • Organophosphorus acid functionalized latex and an aminosilane
    Patent number: 12024646
    Abstract: The present invention relates to a composition comprising a) an aqueous dispersion of polymer particles comprising structural units of a phosphorus acid monomer or a salt thereof; and b) an aminosilane. The composition is effective for improving block resistance in such pigmented coating formulations.
    Type: Grant
    Filed: October 8, 2019
    Date of Patent: July 2, 2024
    Assignees: Rohm and Haas Company, Dow Global Technologies LLC
    Inventors: Azize Ala, Gary Dombrowski, Patrick E. Hartnett, Ozzie Moore Pressley, Qing Zhang
  • LATEX COMPOSITION CONTAINING AN AMINOSILANE AND AN ANION EXCHANGE RESIN
    Publication number: 20210355340
    Abstract: The present invention relates to a composition comprising an aqueous dispersion of polymer particles; b) anion exchange resin particles; and c) an aminosilane. The composition achieves a more desirable balance of stain blocking and stain removal properties in pigmented coating formulations over compositions that contain the latex and the aminosilane but no anion exchange resin, or the latex and the ion exchange resin but no aminosilane.
