Heat Sink Fin Bonding Epoxy Adhesive

January 16, 2019

70-3812NC provides amazing structural strength when bonding aluminum fins to aluminum base plates.  Many heat sink manufacturers are switching to this thermally conductive heat sink adhesive due to its 2,500 psi tensile lap shear strength (aluminum to aluminum).  The 70-3812NC Aluminum Filled Epoxy is the go-to material for heat sink bonding.

In addition to providing strong bonds and thermal conductivity, the 70-3812NC passes NASA's outgassiing requirements per ASTM E-595-07.  This is a two component epoxy system formulated to be cured at room temperature or with mild heat.  The 10:1 mix ratio is easy for batch mixing or utilizing Meter Mix and Dispense Equipment.
