Sumitomo Osaka cement develops epoxy resin suitable for LED lighting

The day before, Japan Sumitomo Osaka cement and Japan Lichang industrial joint development of a liquid epoxy resin "Rico Zi-ma inus", the product in order to ensure the electrical insulation and increase thermal conductivity. The maximum thermal conductivity is 7.3W/m, K, which is about 40 times higher than that of the general epoxy resin. According to reports, the heat dissipation is close to the metal oxide, can be used for LED lighting fixtures, motors and power devices, such as cooling parts.

The product will be used in the main material and hardening material by the ratio of 1 to 1, in order to make it hot hardening of the "liquid type", as well as the main material and hot hardening material has been mixed with the "1 liquid type" of the two kinds of. As a standard, the 2 liquid type has a thermal conductivity of 1, 2, 4, 7W/m, K of the 4, the liquid type has a thermal conductivity of 1, 2, 4W/m, K of the 3 kinds. The development of the product, the specific resistance of up to 1013 + cm, to ensure the electrical insulation. 75 degrees above the viscosity is less than 15Pa * s. Due to the need of 120 to 130 DEG C temperature, through several hours of heat treatment for thermal hardening, therefore, the formation of sufficient liquidity.

In order to achieve the above 3 characteristics, the company in the epoxy resin mixed with high electrical insulation, and has a high thermal conductivity of metal oxide filler. The filler is used as a crosslinking agent for other metal oxides, and is added to the alumina particles with a thermal conductivity of up to 20W/m / K.

Add the amount of metal oxide filler for a total weight of 75% ~ 90% days ago, Japan, Osaka and Japan Sumitomo cement Lichang industrial joint development of a liquid epoxy resin "Rico Zi-ma inus", the product in order to ensure the electrical insulation and increase thermal conductivity.

The filler is used as a crosslinking agent for other metal oxides, and is added to the alumina particles with a thermal conductivity of up to 20W/m / K.

The total amount of metal oxide filler is 75% ~ 90%, which accounts for more than half of the weight of the product. The viscosity of the ordinary epoxy resin is higher, and the formability will gradually become worse. As a result, the company developed a mixed metal oxide filler when the viscosity of epoxy resin and mixed process. However, technical details can not be disclosed.
