THIS PAPER DEALS WITH THE DEVELOPMENT OF ORGANIC COATINGS AS FILM FORMERS FOR THE INTERIOR AND EXTERIOR OF TWO-PIECE DWI, DRD, AND TRIPLE DRAWN FOOD CANS. IT IS NOW WIDELY RECOGNIZED BY THE FOOD CAN INDUSTRY THAT THE TWO- PIECE CAN TECHNOLOGY OFFERS SIGNIFICANT ADVANTAGES IN COST AND PACKED PRODUCT PROTECTION OVER THE TRADITIONALLY USED THREE-PIECE CONTAINERS. COATINGS DEVELOPED TO MEET THE PERFORMANCE REQUIREMENTS FOR THE INTERIOR OF TWO-PIECE DWI CANS INCLUDE A COMBINATION OF EPOXY, ACRYLIC, AND AN ALKOXYLATED MELAMINE. IN THE U.S., COATINGS FOR DRD, DTR OR TRIPLE-DRAWN CANS ARE BASED EITHER ON VINYL ORGANOSOLS OR EPOXY WHICH IS APPROPRIATELY COMPOUNDED AND CROSSLINKED.
