摘要：
Coating compositions that have resistance to sulfur staining along with corrosion resistance are disclosed. The coating compositions comprise a blend of: (a) one or more carboxylic acid group-containing polymers, (b) a dispersion of zinc oxide in a polysilicone resin. The coating compositions are typically applied to the internal surface of a steel can.
