*Heat-resistant and heat-conductive epoxy *Used for manufacturing heat sinks with excellent adhesion and low viscosity *High-performance material that passed NASA's outgassing test
This is a two-component epoxy adhesive containing aluminum, used for tools and parts that need to withstand high temperatures, or for materials requiring high thermal conductivity and heat resistance. It achieves excellent high thermal conductivity through its unique fillers, particle size, and dispersion technology. The 70-3812RNC is popular for various heat sink applications due to its good thermal conductivity. Common applications in heat sinks include bonding fins to bases, folding fin sets to bases, pin fin sets to bases, and cold plate tubes to extruded bases. It passes NASA's low outgassing test (ASTM E-595-07) and is suitable for use in outer space.
