Thermally Conductive Adhesive is a type of polymeric colloidal material primarily used for bonding the surfaces of two materials, possessing multiple functions such as thermal conductivity, insulation, and sealing. It is a one-component moisture-curing thermally conductive material that undergoes condensation reactions with moisture in the air, releasing low molecular weight compounds to initiate crosslinking and curing, thereby forming a high-performance elastomer.

The characteristics of thermally conductive adhesive are mainly embodied in the following aspects:

Adhesion and Thermal Conductivity: Thermally conductive adhesive not only exhibits strong adhesive strength, ensuring a stable connection between objects, but also possesses certain thermal conductivity, aiding in heat dissipation. However, achieving both thermal conductivity and adhesive strength can be challenging, as thermally conductive fillers may affect adhesive performance, with thermal conductivity typically ranging from 0.6 to 2.0 W/mK.

Wide Temperature Range: Thermally conductive adhesive can maintain stable performance in environments ranging from -50°C to 200°C, suitable for various high or low-temperature working conditions.

Insulation and Sealing: Thermally conductive adhesive also demonstrates excellent insulation and sealing properties, effectively preventing electrical short circuits and the ingress of moisture, dust, and other impurities, enhancing equipment reliability and service life.

Aging Resistance and Shock Resistance: Thermally conductive adhesive exhibits remarkable resistance to temperature cycling, aging, and shock, capable of adapting to various harsh working environments while maintaining stable adhesion and thermal conductivity.

Ease of Operation: Thermally conductive adhesive cures rapidly and is easy to extrude, facilitating convenient operation and suitability for various manual or mechanical dispensing methods, meeting the needs of various working environments and conditions.

Furthermore, thermally conductive adhesive has extensive applications in fields such as electronic component packaging, LED lighting, power modules, and heat sink fixation. For instance, in the process of electronic component packaging, thermally conductive adhesive can effectively transfer heat from components to heat sinks, preventing damage to components due to prolonged exposure to high temperatures.

In summary, thermally conductive adhesive plays a crucial role in fields such as electronics, electrical appliances, automobiles, and aerospace, due to its unique properties and wide range of applications.
