  • Epoxy resin, epoxy resin compound comprising the same, and radiant heat circuit board using the compound
    Patent number: 9000071
    Abstract: An epoxy resin compound including an epoxy resin, a hardening agent, and an inorganic filler as a main component is provided. The epoxy resin includes an epoxy resin represented by a chemical formula. Therefore, the epoxy resin having a mesogen structure that increases crystallinity is used, and thus thermal conductivity can be increased. Further, the epoxy resin is used as an insulating material for a printed circuit board, and thus a high radiant heat substrate can be provided.
