| 70-3812 NC is a two component, aluminum filled epoxy system. This system is used for making heat resistant tools, parts, or bonds that require the highest thermal conductivity and heat resistance. We have developed this extremely conductive epoxy by formulating it with a unique combination of fillers, particle sizes and dispersion techniques. 70-3812 NC has good heat dissipation making this a popular choice for a variety of heat sink applications. Its viscosity is particularly suited for Fin bonding. 70-3812 NC passes NASA’s outgassing requirements per ASTM E-595-07. Features: Excellent Thermal Conductivity Superior Adhesion Low viscosity allows quick self leveling&& |
