Solvent-free epoxy resin varnish

Shijiazhuang Li Ding Electronic Materials Co., Ltd. LD-401-1 solvent-free epoxy resin varnish I LD-401-1 solvent-free epoxy resin varnish mix viscosity is low, impregnation, suitable for trickle coil. It can be used with the appropriate time, curing electrical performance, excellent mechanical properties. According to user requirements solventless epoxy insulating paint designed to A, E, B, F, H, such as different levels of heat-resistant products. LD-401-1 solvent-free epoxy insulating paint products have done the same industry-leading level in China, and issued by the national epoxy insulating paint product testing report. Appearance and characteristics:?? LD-401-1A LD-401-1B Viscosity (40 ℃ Cps) 10000-12000 30-35 gray-brown color ???? a mixing ratio of:?? A: B = 100: 20 two use: such as LD-401-1A / B solvent-free epoxy resin varnish of high viscosity can be LD-401-1 A component preheated to 60 ℃, then was mixed with B evenly, then brushing or trickle has been preheated to 100 ℃ of the coil, Tuyun evacuation curing oven. Third, the curing conditions: 120 ℃ × 1 hours and forty, a time: 1 hour (at room temperature) V. curing characteristics: Compressive strength kg / mm2 11 Tensile strength kg / mm2 6 Water absorption 25 ℃%  20 surface resistivity Ω 4.8 × 1015 Volume resistivity Ωcm ?? 2.2 × 1016 3.8 permittivity dielectric loss tangent 1KHz 8.2 × 10-3 VI, storage period:? cool and ventilated storage, shelf life 6 months. _____________________________________________________________________ Address: High-tech District, Shijiazhuang City, Xiangjiang Road 319 Tianshan Science and Technology Industrial Park 6-1-502 Tel: 18931865367
