Abstract:
A coating composition for a food or beverage can that includes an emulsion polymerized latex polymer formed by combining an ethylenically unsaturated monomer component with an aqueous dispersion of a water-dispersible polymer.

Claim (Index 40):
An interior can coating composition comprising a latex-based acrylic coating composition that comprises a surfactant, a crosslinker, and a latex; wherein the latex includes one or more polymers formed from ethylenically unsaturated monomers; wherein the ethylenically unsaturated monomers include one or more monomers selected from alkyl acrylates and methacrylates, one or more acid-functional monomers, optionally one or more oxirane-group containing monomers, and optionally one or more difunctional (meth)acrylate monomers; wherein acrylamide, methacrylamide, N-isobutoxymethyl acrylamide, or N-butoxymethyl acrylamide are not present in ethylenically unsaturated monomers polymerized in aqueous medium to form the latex; wherein the coating composition is not made using PVC compounds and is substantially free of mobile and bound bisphenol A; and wherein the coating composition, when spray applied onto an interior of a 12 ounce two-piece drawn and ironed aluminum beverage can at 120 to 130 milligrams per can coating weight and cured at 188\u00b0 C. to 199\u00b0 C. (measured at the can dome) for 30 seconds, exhibits:\n (i) a global extraction result of less than 50 ppm; and \n (ii) a metal exposure of less than 3 mA on average when the can is filled with 1% NaCl in deionized water and tested pursuant to the Initial Metal Exposure test method disclosed herein.
