PRODUCT DESCRIPTION产品介绍
G-6222A/B is a fast curing,water-white epoxy casting compound designed for encapsulating L.E.D. lamps and displays. The mixed compound will develop high strength, moisture resistant castings with excellent thermal shock properties after a short post cure of 2 hours @ 125℃. G-6222A/B can be colored and diffused by the addition of specific dye concentrates.
G-6222A/B是一种用于L.E.D.灯饰和显示屏封装的快速固化，水白色环氧铸造混合物。当经过2个小时125℃固化后，就成了具有高强度，良好的防潮及抗热振性能的铸件。通过添加特殊的染色试剂和分散试剂，G-6222A/B具有更好的着色和扩散性能。
