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.

Abstract: An aqueous coating composition is provided that is preferably substantially free of styrene and structural units derived from styrene. The coating composition includes a resin system that preferably includes a water-dispersible polymer and an emulsion polymerized ethylenically unsaturated monomer component. The resin system is preferably formed using a process that includes emulsion polymerizing the ethylenically unsaturated monomer component in the presence of an aqueous dispersion including the water-dispersible polymer. In certain preferred embodiments, the water-dispersible polymer is a salt of an acid- or anhydride-functional aromatic polyether polymer.

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.

Abstract: The present invention relates to strategies by which one or more phenolic resins are provided in aqueous phenolic dispersions in a manner so that the resultant aqueous phenolic dispersions are more easily combined with water-based latex compositions. The principles of the present invention make it much easier to formulate water-based latex compositions in which substantial phenolic resin content can be stably dispersed for long periods of time. In one aspect, the present invention relates to a method of making a coating composition, comprising a) providing an inverted aqueous dispersion comprising i) at least one polymer having one or more polar, hydrophilic groups; and ii) at least one phenolic resin; b) providing a latex composition; and c) blending the latex composition with the aqueous dispersion to form the coating composition.
