  • Coating composition for metal containers
    Patent number: 5776569
    Abstract: A coating composition for metal containers, a method of coating a metal container, and a metal article useful as a food or beverage container are disclosed. The coating composition for metal container interiors and exteriors comprises: (a) a low molecular weight polyfunctional epoxy novolac resin; (b) a phenolic resin; (c) a solution grade vinyl chloride copolymer, a high molecular weight epoxy resin or a mixture thereof; (d) about 60% to about 90% by weight of nonvolatile material of a vinyl chloride dispersion resin; and a nonaqueous carrier. The coating composition is stored as a single unit system from manufacture until use without an unacceptable increase in viscosity.
    Type: Grant

  • Metal container coated with a composition comprising an acrylic polymer latex, melamine formaldehyde resin and a phenol formaldehyde resin
    Patent number: 5139834
    Abstract: Water borne, water dilutable metal can coating compositions containing (A) an acrylic polymer latex including an alkyloxymethylacrylamide or -methacrylamide monomer, (B) a melamine/formaldehyde resin, (C) an alkanolamine treated phenol/formaldehyde resin, (D) a lubricant and (E) a defoamer in a water or water/organic solvent mixture are provided. These compositions cure between 15 seconds and 1 minute at moderate can coating cure temperature and permit faster can coating machine speeds on Rutherford can coating machines.
