  • Publication number: 20230047189
    Abstract: An aqueous coating composition is provided that is useful in coating a variety of substrates, including interior or exterior portions of food or beverage cans. The coating composition includes a resin system that includes a multi-stage latex. In some embodiments, the multi-stage latex is formed using a process that includes emulsion polymerizing two or more stages in the presence of an aqueous dispersion including a water-dispersible polymer. In certain preferred embodiments, the water-dispersible polymer is a polyether polymer.

  • Publication number: 20230044013
    Abstract: An aqueous coating composition useful in coating a variety of substrates, including interior or exterior portions of food or beverage cans. The coating composition includes a multi-stage polymeric latex having two or more emulsion polymerized stages in an aqueous carrier liquid, wherein the latex has one or both of: (i) a lower glass transition temperature (Tg) emulsion polymerized stage having a calculated Tg that is at least 20° C. lower than a calculated Tg of a higher Tg emulsion polymerized stage, or (ii) a gradient Tg with at least a 20° C. differential in the calculated Tg of monomers fed at the start of polymerization compared to monomers fed at the end of polymerization. When spray-applied on the interior of a food or beverage can, the composition exhibits a global extraction result of less than 50 ppm and a metal exposure value of less than 3 mA.

  • Publication number: 20190249029
    Abstract: A coating composition is provided that is preferably substantially free of bisphenol A. The coating composition is useful in coating metal substrates such as, for example, interior and/or exterior surfaces of food or beverage cans. In some embodiments, the coating composition is formulated using an acrylic polymer that is formed form ingredients that do not include styrene.
