摘要： A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes an emulsion-polymerized latex copolymer having copolymer chains of one or more ethylenically-unsaturated monomers and one or more styrene offset monomers. Preferably, the coating composition is substantially free of BPA, PVC, and styrene. The method may also include curing the sprayed coating composition, thereby providing the coating on the interior surface of the food or beverage container.

摘要： A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes an emulsion-polymerized latex copolymer having copolymer chains of one or more mono-unsaturated monomers that are cross-linked with one or more multi-unsaturated monomers. The method also includes heating the sprayed coating composition to cure the coating composition, thereby providing the coating on the interior surface of the food or beverage container.

摘要： Metal food or beverage containers are coated with a polyether polymer containing at least two ether linkages in the polymer backbone. The polymer is substantially free of segments derived from bisphenol A and epoxides thereof, and is a reaction product of, or can be derived from, (i) an aryl- or heteroaryl-group-containing diepoxide that is not derived from a polyhydric phenol or a glycidyl ester and (ii) a polymer backbone extender that has two functional groups reactive with an epoxy group and which following reaction with the diepoxide provides at least one pendant aryl or heteroaryl group on the polymer backbone, or provides at least one divalent aryl or heteroaryl group in the polymer backbone and linked to the backbone via ether linkages.
