Beschreibung
Zusammenfassung:	A water-based barrier coating composition is disclosed that has improved barrier performance and enhanced stability. The water-based coating composition comprises a polymeric binder and an amine stabilizer, wherein the pH of the composition is equal to or greater than the pKa of the amine stabilizer. When desired, the disclosed coating composition may further include standard low-cost fillers, layered fillers capable of being at least partially exfoliated, nanoparticle fillers, or mixtures thereof. A multilayer product comprising a layer of the disclosed water-based coating composition is also disclosed that has enhanced oxygen barrier performance.
