EPOXIDAMIN BARRIERÜBERZÜGE MIT ARYLOXY- ODER ARYLOATGRUPPEN

摘要

Polyepoxide-polyamine gas barrier coatings for use on packaging materials such as polymeric containers are provided with low permeability at relatively low amine to epoxy cure ratios by including substantial aryloxy or aryloate group content. The aryloxy or aryloate content may be provided, for example, by polyglycidyl ether of resorcinol or polyglycidyl ester of phthalic acid.
