COATING MATERIALS FOR BISPHENOL A-CONTAINING POLYMERS

摘要

The present technology provides compositions that may be coated on bisphenol A-containing polymers to provide a coating or film that prevents bisphenol A from leaching from the polymer. Coatings using the present compositions also protect the bisphenol A-containing polymer from degradation by UV rays and other sources. The compositions include one or more matrix polymers having a solubility parameter of about 20 or less; and a plurality of UV-blocking nanoparticles dispersed in the one or more matrix polymers; wherein the composition is substantially free of bisphenol A. Methods of making the compositions and coatings are also provided. The coatings may be used on food and beverage containers made from bisphenol A-containing polymers.
