ABSTRACT:
Single package C-enamel can coatings of improved stability are prepared by first dispersing the zinc oxide pigment in a water compatible solvent containing a butylated urea formaldehyde or butylated melamine and adding the dispersed pigment to a vehicle comprising an aqueous blend of an epoxy-acrylic emulsion with an acrylic latex. The stability improvement is evident in the coating viscosity, the non-settling of the pigment on storage, and the flexibility adhesion in the applied coating.
