摘要： The present invention provides coating systems that use polycyclic polyester resins in combination with phenolic resins. The combination of these resin materials provides a coating composition that provides cured coatings with excellent adhesion, blush resistance, stain resistance, and corrosion resistance in a single coating composition. This makes the coating compositions well suited for use to form coatings on closures used in the packaging industry for food and beverages. In many embodiments, even though PVC and BPA materials are excluded, the coating compositions provide monocoats whose performance substantially matches and even exceeds the performance of monocoats formed from PVC and BPA containing materials.
