  • Patent number: 5684083
    Abstract: A composition is disclosed which includes a urethane resin containing reactive ethylenically unsaturated groups and hydroxyl groups, which is preferably derived by reacting a polyisocyanate and an isocyanate reactive group-containing unsaturated monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, hydroxyalkyl acrylamides, hydroxy functional allylic compounds, and mixtures thereof to form an isocyanate group-containing reaction product which is then reacted with an organic polyol wherein the equivalent number of hydroxyl groups is in excess compared with the equivalent number of isocyanate groups. The composition also includes an aminoplast resin for reaction with hydroxyl groups on the urethane resin in an amount of less than about 10% by weight based on solids of the composition which is effective in thin film curing of the composition.
    Type: Grant
    Filed: May 22, 1995
    Date of Patent: November 4, 1997
    Assignee: PPG Industries, Inc.
    Inventors: Rodger G. Temple, Henry H. Crum, III, Jonathan T. Martz

  • Patent number: 5166272
    Abstract: A stable emulsion polymer is prepared by the emulsion polymerization of a vinyl monomer component in the presence of a base neutralized copolymer having a peak molecular weight not exceeding 50,000 of an olefinically unsaturated material selected from the group consisting of 1-decene, 1-dodecene, undecenylic acid and mixtures thereof and an ethylenically unsaturated anhydride containing material. The emulsion polymer is particularly useful for preparing coating compositions which have excellent physical properties.
