POLYVINYL ALCOHOL AND ETHYLENE VINYL ALCOHOL COPOLYMER BARRIER COATINGS

摘要

Barrier coatings with efficacy against oxygen and nuisance substances are described that comprise lower molecular weight PVOH and EVOH co-polymers, when coated on flexible substrates. Coating formulations comprising these co-polymers advantageously tolerate moderate to higher proportions of organic solvents in aqueous blends, and thus produce faster drying coating formulations.
