  • Patent number: 11795250
    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.

  • 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.

  • Patent number: 9981287
    Abstract: Coating compositions and methods of using these compositions to form tough, abrasion resistant, and water resistant coatings on metal-containing substrates are described. Coating compositions are derived from one or more ingredients comprising at least one copolymer, referred to herein as Copolymer I, that preferably comprises (a) one or more repeating units (Repeating Unit(s) A) comprising at least one hydrophilic ester functionality and at least one polar functionality; and (b) one or more additional kinds of copolymerizable repeating units (Repeating Unit(s) B). Preferably, repeating Unit(s) A are a residue of an unsaturated monoester of a diacid or anhydride thereof having a carbon-carbon double bond, wherein at least one hydrophilic ester is pendant from a first carbon of the carbon-carbon double bond and at least on polar group is pendant from the second carbon of the carbon-carbon double bond.
