Black Color PCB Electronic Potting thermal conductive Silicone rubber


the silicone can be applied to the sealing and pouring of various electronic components, and then forming insulation system with no corrosion and negligible shrinkage.



the silicone Is suitable for bonded seal of electronic components, power module and control module, LED invertor potting, etc which requires waterproof and insulation. It can be broadly used for LED screen, Wind Power Generator, PCBSubstrate, etc. 




Room temperature vulcanize, and easy to operate;

Maintain flexibility at a wide temperature range, and excellent insulation performance;

Waterproof, moisture-proof, mouldproof, dustproof, and stable components;

Resistance to Chemical dielectric, anti-yellowing, resistance to climate ageing.

Warm Tips for for PCB Electronic Potting Silicone
 1. Sealing pakage for storage. the mixture should be used up at once to avoid wasting.
 2. Silicone belongs to non-dangerous goods, but keep away form mouth and eyes.
 3. When it gets stratified after a period of storage, Please mix HY-210# evenly before using,
      it does not affect the performance.

Package for for PCB Electronic Potting Silicone



Shelf Life and Transportation
1. Twelve(12) months when stored at 25C in original unopened packages.
2. this is a non-dangerous product, it can be transported as general chemicals.
3. Products exceed the storage life should be confirmed normal before using.


Technical Guidelines
1. Pls put part A and B in separate container and stir evenly before mixing the two
   parts together.
2. Mixing Ratio part A:part B is 10:1
3. Bubble release if necessary, deaeration the mixture under 0.08 MPa for 3 minutes.
4. HY-215# is cured at roon temperature, so pls put it under room temperature after
   pouring. It comes to next process when basically cured, and it takes about 24 hours
   for completely cured.
