  • High-solids thermosetting enamel coating composition
    Patent number: 4338379
    Abstract: A thermosetting coating composition, useful as an automotive finish, has film-forming constituents of a low molecular weight hydroxyl-functional acrylic copolymer, a low molecular weight hydroxyl-functional polyester based on branched-chain glycols, and an aminoplast resin. The composition can be applied at environmentally-acceptable solids levels and cured at commercially acceptable temperatures to form a durable film.
    Type: Grant
    Filed: February 13, 1981
    Date of Patent: July 6, 1982
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Clifford H. Strolle, Glenn D. Thornley
  • High-solids polyester and aminoplast coating composition
    Patent number: 4316940
    Abstract: A curable, high-solids coating composition has film-forming constituents of a low molecular weight hydroxyl-functional polyester based on branched-chain glycols, an epoxy-resin/acid ester, and an aminoplast resin. The composition can be applied at commercially acceptable temperatures and environmentally acceptable solvent levels to form a durable film.
    Type: Grant
    Filed: August 7, 1980

  • High-solids polyurethane enamel coating composition
    Patent number: 4281078
    Abstract: A coating composition of a urethane polymer has film-forming constituents of an organic polyisocyanate, a low molecular weight hydroxyl-functional acrylic copolymer, and a low molecular weight hydroxyl-functional polyester based on branched-chain glycols. The composition can be applied at environmentally-acceptable solids levels and cured at ambient temperatures to form a durable film.
