  • Phosphate epoxy acrylic copolymers
    Patent number: 4600754
    Abstract: Water dispersed phosphated epoxy-acrylic polymers are produced by first producing an epoxy phosphate followed by in-situ polymerization of ethylenically unsaturated monomers, including carboxyl monomers, in the presence of the epoxy phosphate and utilizing at least 3% peroxide catalyst based on the weight of monomers.
    Type: Grant
    Filed: May 10, 1984
    Date of Patent: July 15, 1986
    Assignee: SCM Corporation
    Inventor: Peter P. Winner
  • Aqueous self-curing polymeric blends
    Patent number: 4522961
    Abstract: The invention pertains to coating compositions comprising self-curing water-dispersed polymers, epoxy-acrylic copolymers, and preferably including epoxy phosphate polymers. The self-curing water-dispersed polymers produced preferably by step-wise polymerization of ethylenically unsaturated monomers comprising alkylol acrylamide monomer, functional monomers, and other monomers, wherein the alkylol acrylamide monomers are copolymerized in the second stage monomer addition to preferentially locate alkylol acrylamide groups in the surface portion of the latex polymer particles. Melamine resins can be added to improve the cure properties of the coating composition. The coating compositions are advantageously sprayable compositions and are particularly useful for interior coatings for food and beverage containers.

  • Aqueous self-curing polymeric blends
    Patent number: 4487860
    Abstract: The composition comprises an aqueous polyelectrolyte polymer intermixed with a phosphated polymer and a self-curing water dispersed polymer containing copolymerized functional monomer and alkylol acrylamide monomer. The polyelectrolyte polymer is produced by copolymerizing ethylenically unsaturated monomers, including hydroxyl or carboxyl monomers in the presence of an ionizing agent.
