  • 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.

  • Patent number: 9181448
    Abstract: Latex emulsions are disclosed which can be used in the formation of coating compositions that are not water sensitive, have good blush resistance and retortability. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Coating compositions of the invention may be prepared by polymerizing at least one ethylenically unsaturated monomer component, a stabilizer comprising a strong acid and an initiator in a carrier to form an emulsion, polymerizing the emulsion with at least one different ethylenically unsaturated monomer component to prepare the composite latex emulsion, and reacting the composite latex emulsion with a neutralizer to form the coating composition. Methods of coating substrates with the coating compositions, and substrates coated with the coating compositions are also disclosed.
