  • Low temperature curing thermosetting coatings for solvent-sensitive moldings
    Patent number: 4404308
    Abstract: A low temperature curing solution coating composition is disclosed for the protection of solvent-sensitive thermoplastic moldings. In these compositions, a solvent medium consisting essentially of alcoholic solvents has dissolved therein a self-curing solution copolymer of monoethylenically unsaturated monomers containing an ether of an N-methylol functional monomer, especially isobutoxymethyl acrylamide. This solution is catalyzed with from 3% to 12%, based on the weight of the copolymer, of a long chain dialkyl naphthalene disulfonic acid. The catalyzed compositions are stable and cure at 150.degree. F. to 200.degree. F. without damaging the thermoplastic moldings.
    Type: Grant
    Filed: May 24, 1982
    Date of Patent: September 13, 1983
    Assignee: DeSoto, Inc.
    Inventors: Frank J. Ragas, Ralph L. Minnis, Edward J. Murphy, Steve J. Vargo
  • Low temperature curing thermosetting coatings for solvent-sensitive moldings
    Patent number: 4331719
    Abstract: A low temperature curing solution coating composition is disclosed for the protection of solvent-sensitive thermoplastic moldings. In these compositions, a solvent medium consisting essentially of alcoholic solvents has dissolved therein a self-curing solution copolymer of monoethylenically unsaturated monomers containing an ether of an N-methylol functional monomer, especially isobutoxymethyl acrylamide. This solution is catalyzed with from 0.5% to 2.0%, based on the weight of the copolymer, of sulfuric acid. The catalyzed compositions are stable and cure at 150.degree. F. to 200.degree. F. without damaging the thermoplastic moldings.
