VS-TP1001
VOLSUN
VS-TP1001 is a specialized two-component heat-conductive potting compound material that cures into elastic silicone rubber. It is designed for electronic and electrical products and modules, providing protection for high-power power supply modules, frequency converters, sensors, and ensuring secure connection and fixation between on-board electronic devices and PCBs. This silicone potting compound can be cured at room temperature or through heating, making it versatile for various applications in the electronics industry.
Wide operating temperature range of -70℃ to +200℃
Outstanding mechanical properties and flexibility
Superior thermal conductivity and resistance to aging
Self-leveling with low viscosity, making it easy to fill seams and drill
Good adhesion to metals and plastics, with low modulus and stress for added durability and reliability

Stir components A and B separately before mixing
Combine the well-stirred components A and B in a 1:1 ratio (either volume or weight)
Pour the mixed compound into the device to be filled and allow it to cure (can be cured at room temperature or with heat)
To ensure even distribution of fillers, it is essential to stir components A and B separately before mixing to achieve a uniform blend.
Once components A and B are mixed, they will undergo a reaction and cure process, making it crucial to use the mixture promptly without attempting to reuse it after curing.
Prior to pouring the mixture into the protective part, ensure the absence of large debris or contaminants to maintain optimal material adhesion.
During the curing process, avoid contact with external objects that could impact the material's appearance and protective properties until it is fully cured.
Avoid contact with eyes and mouth. In case of accidental exposure, rinse with clean water or seek medical attention.
Vacuum defoaming is necessary for achieving high thermal conductivity before pouring the mixture.
Note that curing time may be prolonged in low-temperature environments.
Store products in their original packaging with the lid tightly closed to prevent contamination, maintaining a temperature range of 15℃ to 30℃ and relative humidity below 70%.
The shelf life of the product is 9 months from the date of production.
