Abstract:
A coating composition is provided for use in laminate substrates useful in packaging of liquids and solids where the coating provides and increased resistance to the permeability of gases such as oxygen and carbon dioxide. In one embodiment the coating composition is a dispersion or a solution that comprises at least one hydroxyl functional polyetheramine, phosphoric acid and a defoamer. The backbone of the polyetheramine has diglycidyl ether linkages that comprise about 5 to about 70 mole percent resorcinol diglycidyl ether. The coating composition can be applied to substrates by coating applications such as spraying, rolling reverse and direct, rolling direct and reverse gravure, kiss coat, flow coating, brushing, dipping and curtain-wall coating, for example.
