Abstract
Food and beverage containers and methods of coating are provided. The food and beverage containers include a metal substrate that is at least partially coated with a coating composition that includes a water-dispersible resin system and an aqueous carrier. The resin system includes an epoxy component and an acrylic component. In a preferred embodiment, the coating composition is at least minimally retortable when cured.
Claims20
A coated article comprising:
- a food or beverage container, or a portion thereof, including:
- a metal substrate;
- and
- a coating composition applied to at least a portion of the metal substrate, the coating including:
- a water-dispersible resin system comprising:
- an epoxy component, and
- an acrylic component having a Tg of from 40° C. to 160° C.,
- wherein at least some of the epoxy component and the acrylic component are present in a copolymer in which a carbon atom of a backbone of the epoxy component is covalently attached to a carbon atom of a backbone of the acrylic component;
- and
- an aqueous carrier.
