Abstract
A coating composition comprising: a. a polyester imide (PEI) polymer having an acid value of ≥10 mg KOH/g; and b. a crosslinker operable to crosslink the acid functionality on the polyester imide polymer wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
Claims24
A food and/or beverage container coated on at least a portion thereof with a coating, wherein the coating is derived from a coating composition comprising:
- a. a polyester imide (PEI) polymer having an acid value of ≥10 mg KOH/g;
- and
- b. a crosslinker comprising a hydroxyalkyl amide, a hydroxyalkyl urea and/or a carbodiimide;
- wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
A monobloc aerosol can and/or tube coated on at least a portion thereof with a coating, wherein the coating is derived from a coating composition comprising:
- a. a polyester imide (PEI) polymer having an acid value of ≥10 mg KOH/g;
- and
- b. a crosslinker comprising a hydroxyalkyl amide, a hydroxyalkyl urea and/or a carbodiimide;
- wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
