    摘要： Expandable, thermally curable compositions containing at least one epoxy resin, at least one polyester, at least one blowing agent, and at least one curing agent are useful as adhesives and structural reinforcement materials. When foamed and adhered to a metal substrate surface, such polyester-modified foamable compositions can exhibit improved adhesion to the substrate surface after exposure to a corrosive environment, as compared to compositions that do not contain polyester. Furthermore, these compositions can exhibit improved flow properties in the uncured state at temperatures between 50 and 100° C. They are granulatable, with the granules produced thereby having non-tacky surfaces at room temperature and being capable of being readily processed into molded objects by injection molding processes.

    摘要翻译： 包含至少一种环氧树脂，至少一种聚酯，至少一种发泡剂和至少一种固化剂的可膨胀的可热固化组合物可用作粘合剂和结构增强材料。 当发泡并粘附到金属基材表面时，与不含聚酯的组合物相比，这种聚酯改性的可发泡组合物可以在暴露于腐蚀性环境之后表现出改进的对基材表面的粘合性。 此外，这些组合物可以在50至100℃的温度下在未固化状态下表现出改进的流动性。它们是可成粒的，由此产生的颗粒在室温下具有非粘性表面，并且能够容易地通过 注塑工艺。
