Title
(EN) Gas barrier compositions having improved barrier properties
(ZH) 具有改进的阻挡性能的气体阻挡组合物
Abstract
(EN) Gas barrier coating compositions are provided which include a polyamine component, a polyepoxide component and a hydroxy-substituted aromatic compound that is present in an amount sufficient to provide a gas barrier coating having an oxygen permeability less than or equal to 75 percent of the oxygen permeability of the same composition without a hydroxy-substituted aromatic compound. Also provided is a multi-layer packaging material having at least one gas permeable packaging material layer and at least one gas barrier material layer formed from the gas barrier coating composition. Sealable containers are also provided.
(ZH)

提供包括多胺组分、聚环氧化物组分和含羟基取代的芳族化合物的气体阻挡涂料组合物,该羟基取代的芳族化合物的存在量足以提供具有氧渗透性能低于或等于无该羟基取代的芳族化合物的相同组合物的透氧性的75%的气体阻挡涂层。还提供一种具有至少一气体可渗透包装材料层和至少一由该气体阻挡涂料组合物形成的气体阻挡材料层的多层包装材料。还提供密封容器。
