  • Patent number: 9617446
    Abstract: Coating compositions are disclosed having a non-bisphenol A based film forming resin and an adhesion promoter resin. The coating compositions provide an alternate to epoxy resins that still allow melamine formaldehyde free cure, blush resistance, capability to retort and can withstand hard-to-hold beverages. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Substrates can be coated by preparing an adhesion promoter composition by a method including mixing an epoxidized resin and a solvent to form a mixture, adding a phosphoric acid compound to the resulting mixture to form a phosphate ester, adding water to partially hydrolyze the phosphate ester, and adding a neutralizer to form the adhesion promoter resin, followed by blending the adhesion promoter resin with a non-bisphenol A based film forming resin to form a coating composition, and applying the coating composition to the substrate.
