1. A method, comprising the steps of:
receiving a coating composition that includes an emulsion polymerized latex polymer that comprises a reaction product of an ethylenically unsaturated monomer component polymerized in the presence of an aqueous dispersion of a salt of an acid- or anhydride-functional polymer, wherein the ethylenically unsaturated monomer component includes an oxirane group-containing monomer and at least 40 wt-% of the ethylenically unsaturated monomer component comprises one or more monomers selected from alkyl acrylates and methacrylates, and wherein the coating composition is substantially free of bound BPA; spray applying the coating composition onto an interior surface of an aluminum beverage can including a body portion and a bottom end portion; and curing the coating composition to form a continuous cured coating. |
