The 70-3812NC aluminum-filled epoxy adhesive has been designed for bonding heat sinks that require high-thermal conductivity and strong structural bonds. Common heat sink bonding applications include fin to base, folded-fin set to base, pin-fin set to base, and cold plate tube to extruded base.
In addition to providing bonds and thermal conductivity, the 70-3812NC reportedly passes NASA’S outgassing requirements per ASTM E-595-07. The 70-3812NC is a two-component epoxy system formulated to be cured at room temperature or with mild heat. The adhesive has a 10:1 mix ratio for batch mixing or utilizing meter mix and dispense equipment.
