TERADA TERADITE TE-7128 Two-Component Flame-Retardant Epoxy Resin for Electronic Insulation & Protection
Product Introduction TERADITE TE-7128 is a two-component functional epoxy resin developed by Terada Co., Ltd. It belongs to the TERADITE Functional Resin series and is primarily designed for the insulation and protection of electronic components. TE-7128 uses a simple 100:100 resin-to-hardener mixing ratio. At 25°C, the resin viscosity is approximately 50,000 mPa·s, the hardener viscosity is approximately 8,000 mPa·s, and the mixed viscosity is approximately 20,000 mPa·s. After curing, the material provides a Shore D hardness of approximately 92, a glass transition temperature of approximately 155°C, and a coefficient of thermal expansion of approximately 25 ppm/K. It also provides flame-retardant performance equivalent to UL94 V-0 at 1 mm thickness, making it suitable for demanding electronic protection applications.
