汉高公司推出新型硅胶粘合剂

汉高公司(www.loctite.com)推出一系列单组分光线和水气固化硅胶粘合剂,适合用于含有硅树脂材料或者需要高弹性粘合连接或者涂层的医疗器械。新系列的3种产品若接触到合适的紫外线/可见光光源,均可在30秒内固化。

采用这种医用硅树脂粘合剂,部件无需放在货架上等待固化,可以立即进行质量测试。该粘合剂在硅树脂和聚碳酸酯等塑料材料上可产生很高的粘合强度,可确保组装牢固。这种硅树脂固化状态下的撕裂强度超过50磅/英寸,延伸率超过140%,从而形成坚韧而又弹性十足的粘合线,适合用于导管、呼吸设备和连接器、医用导管以及气管切开器械。

Loctite 5055是一种低粘度的浅黄色透明液体,能很好地粘合聚碳酸酯,抗张强度接近1500 psi。Loctite 5056为中等粘度产品,未固化时外观与Loctite 5055类似,固化后能够耐受高温和潮湿环境。这两款新型光线固化硅树脂粘合剂是继年初推出Loctite 5240之后,该产品系列的最新成员。作为一种紫外线/可见光固化硅树脂,Loctite 5240能在阴影区域通过水气实现辅助固化,固化时间为24到72小时。该粘合剂的固化深度为0.75英寸,形成的粘合线无色、透明。

这3种Loctite(R)产品均符合ISO-1093对生物相容性的严格要求,因此适合用于组装医疗器械。
