TERADA TERADITE TE-7817 High-Thermal-Conductivity High-Heat-Resistance Flame-Retardant Epoxy Potting Resin

TERADITE TE-7817 is a two-component high-thermal-conductivity epoxy resin developed by Terada Co., Ltd. It belongs to the TERADITE High Thermal Conductivity Resin series, which is primarily designed for potting of electric and electronic parts. TE-7817 provides a thermal conductivity of approximately 6.5 W/m·K, making it one of the higher thermal-conductivity grades in this product series. Its mixed viscosity is approximately 58,400 mPa·s at 25°C and 20,400 mPa·s at 60°C, with a specific gravity of approximately 3.24. After curing, the resin provides a Shore D hardness of approximately 91, a Tg of approximately 156°C, and a very low CTE of approximately 8 ppm/K. Its volume resistivity is greater than 1×10¹⁵ Ω·cm, allowing the material to combine high thermal conductivity with electrical insulation. The recommended resin-to-hardener mixing ratio is 100:100.
