Epoxy varnish

Shijiazhuang Li Ding Electronic Materials Co., Ltd. LD-401 solvent-free epoxy resin varnish LD-401 solvent-free epoxy resin varnish having a mixture of low viscosity and good dipping, dipping applies to the coil, the enclosure of the capacitor. It has a longer usable life, curing electrical performance, excellent mechanical properties. It can also be designed as A, E, B, F, H, C, such as different levels of heat-resistant products according to user requirements. Appearance and characteristics: LD-401A LD-401B Viscosity (40 ℃ Cps) 175--250 20-30 a yellow color yellow, mixing ratio: A: B = 100: 80 two, curing conditions: 100 ℃ --110 ℃ × 2 hours, thirty, a time: two days (room temperature) Fourth, the use of technology: the LD-401 solvent-free epoxy resin varnish A proportionally mixed with B, then the workpiece is immersed in the paint; if conditions vacuum impregnation, so better. V. cured Features:?
