Product Overview


Products Description

Thermal Conductive Silicone Adhesive
It is a thermally conductive silicone RTV adhesive rubber developed for heat sink applications.
SS-3941 is a 1-Part silicone that when applied to the substrate enables adhesion to parts and heat transfer of the bonded assembly within minutes.
When cured, the elastomer resists weathering, ozone, moisture, weathering, ozone, moisture, UV and high temperatures.
It works well in manual and automatic dispensing.


Use thermal adhesive paste to glue heat sinks to LEDs, CPUs, and other heat-generating components.

Operation Process

1. The surface of the joint should be free of oil stains, dust, impurities, etc.
2. Cut the glue nozzle into the required size and shape according to the process requirements;
3. Cut off the sealant seal, install the glue nozzle, and put it into the glue gun;
4. Apply the sealant evenly to the joints, the thinnest part is greater than 1mm; when using a pneumatic glue gun, the air pressure is controlled at 0.2~0.4Mpa;
5. The product can be trimmed using traditional methods after the surface is dry.
