  • 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.

  • Patent number: 9593195
    Abstract: Coating compositions can be prepared from an acrylic grafted polyether resin, wherein the smallest difunctional hydroxyl phenyl segment used to form the acrylic grafted polyether resin has a molecular weight greater than about 500, and wherein the smallest difunctional hydroxyl phenyl segment used to form the acrylic grafted polyether resin does not comprise two or more non-impaired hydroxyl groups attached to two or more different five-membered or six-membered carbon atom rings in a segment having a molecular weight less than about 500. The acrylic grafted polyether resin can be prepared by reacting a dihydroxyl compound and/or a diamine compound with a phenol stearic acid compound to produce a diphenol, reacting the diphenol with a diglycidyl ether compound to form a polyether resin, and mixing the polyether resin with an ethylenically unsaturated monomer component in the presence of an initiator to form the acrylic grafted polyether resin.
