    • Polyamide/epoxy thermoplastic-thermoset curable adhesive resin systems which are aqueous dispersions are disclosed. The epoxy resin has an average of about 2 to about 8 unreacted epoxy groups. The polyamide component comprises both an acid terminated polyamide resin and an amine terminated polyamide resin. An additional base to neutralize some of the free acid groups on the polyamide components is present. Optionally the systems contain a water soluble dipolar chemical moiety to provide stability and/or a surfactant. The adhesive resin systems exhibit stability and are capable of forming an adhesive bond at elevated temperatures which then maintains integrity under high temperature, pressure and moisture conditions of autoclave sterilization. They are useful in producing packaging containers for enclosing and isolating an object to be sterilized.
    • 公开了作为水性分散体的聚酰胺/环氧热塑性 - 热固性固化性粘合树脂体系。 环氧树脂平均具有约2至约8个未反应的环氧基团。 聚酰胺组分包括酸封端的聚酰胺树脂和胺封端的聚酰胺树脂。 存在用于中和聚酰胺组分上的一些游离酸基团的另外的碱。 任选地,所述体系含有水溶性偶极化学部分以提供稳定性和/或表面活性剂。 粘合剂树脂体系表现出稳定性,并且能够在升高的温度下形成粘合剂粘合剂,然后在高温灭菌的高温,高压和潮湿条件下保持完整性。 它们可用于生产用于封闭和隔离待消毒物体的包装容器。
