CONATHANE® EN-7和EN-8是双组分、非MBOCA基、高强度液态聚氨酯树脂系统,旨在确保暴露在极端环境中的电气/电子组件的性能。由这些系统制备的弹性体具有以下优异的性能:优异的水解稳定性、低粘度、耐真菌性、优异的介电性能、抗热震性、高强度、高延伸率。建议将这些系统用作电缆、连接器、模块的成型和封装化合物。线绕器件、应变敏感器件以及印刷电路用100%固体涂层。它们对大多数基材的优良粘附性和良好的柔韧性也表明它们可以用作锁固和嵌缝粘合剂。 CONATHANE EN-7 and EN-8 are two-component, non MBOCA based, high strength liquid polyurethane resin systems designed to ensure the performance of electrical/electronic assemblies exposed to severe environmental extremes. Elastomers prepared from these systems exhibit the following outstanding properties: Superior hydrolytic stability Low viscosity Fungus resistance Exceptional dielectric properties Thermal shock resistance High strength High elongation These systems are recommended for use as molding and potting compounds for electrical cables, connectors, modules, wire wound devices, strain sensitive devices, as well as 100% solids coatings for printed circuitry. Their excellent adhesion to most substrates, and good flexibility, also suggest their use as staking and filleting adhesives. |
