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.
