Thermal Adhesives

Thermal adhesives are commonly used to attach a heatsink to electronic components. The glue is typically a two part epoxy resin which cures to form a strong bond. They are thermally conductive and usually electrically insulating and help to dissipate heat from the device.
Its main function is to ensure there is no air space between which would act as a thermal insulator. It fills in the microscopic imperfections on the heatsink and device.
There are other types of products to eliminate the air gap under a heat sink:
• Thermal Grease
• Thermal Gap Pads
