  • Powder coating resin composition containing a dicarbonamide or polycarbonamide condensate
    Patent number: 4190715
    Abstract: A curable powder resin composition comprising an aminoplast and a polyester or polyacrylic resin. The aminoplast is a condensate of a methylolurea or methylolaminotriazine with an aliphatic alcohol and a reactive compound containing at least one reactive group selected from the group consisting of hydroxyl and amide.
    Type: Grant
    Filed: March 17, 1978
    Date of Patent: February 26, 1980
    Assignee: Monsanto Company
    Inventors: Robert A. Isaksen, Frederic J. Locke, John L. Smith, George T. Spitz
  • Powder coating resin process containing an aromatic carbonamide condensate
    Patent number: 4190714
    Abstract: A process for preparing a free-flowing curable powder resin composition with a sintering temperature above 40.degree. C., comprising the steps of condensing a methylolurea or methylolaminotriazine with an aliphatic alcohol and a reactive compound containing hydroxyl or amide groups; blending the condensate with a polyester or polyacrylate; and grinding the blend to a powder of average particle size in the range of 20 to 150 microns.
