  • Coating compositions comprising latex emulsions and hydroxyl functional oil polyol graft copolymers
    Patent number: 9458345
    Abstract: The present invention includes coating compositions and methods for coating substrates using the coating compositions. In some embodiments of the invention, a coating composition is prepared by a method including the steps of a) preparing a latex emulsion by a method including mixing an ethylenically unsaturated monomer component in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the latex emulsion, b) preparing a hydroxyl functional oil graft copolymer by a method including reacting an epoxidized vegetable oil with a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, and reacting the hydroxyl functional oil polyol with an ethylenically unsaturated monomer component in the presence of an initiator to form the hydroxyl functional oil polyol graft copolymer, and c) blending the latex emulsion and a crosslinker then adding the hydroxyl functional oil graft copolymer to form the coating composition.

  • Aqueous dispersed acrylic grafted epoxy polyester protective coatings
    Patent number: 5290828
    Abstract: An aqueous dispersed, low VOC coating containing a polymeric binder comprises an addition copolymer grafted epoxy polyester terpolymer. The graft terpolymer comprises by weight between 1% and 70% unsaturated polyester, 5% and 80% epoxy resin, and 5% and 70% addition copolymer, where the terpolymer has an Acid Number above about 30 and is dispersed into water with a volatile base.
