Si 3317 is one component room temperature curing organic silicone sealant with high elasticity.

No corrosion (alcohols that released in the process of solidification) to the PC, CU and other materials.


Detailed Product Description



  1. Excellent thermal and insulating performance
  2. Good resistance to moisture, dust. corona and buffering to earthquake.
  3. Stable resistance to high and low temperature(-60~260°C)
  4. Outstanding aging resistance. The period of validity could be 10-20 years
  5. No yellowing and leakage after cured. Good comprehensive performance.


  1. as heat—conducting medium of electronic parts and components when needed.
  2. as filling compound between power transistor, thyristor diode and their base material (aluminum, Cu)




  1. Cleaning: cleaning the surfaces that to be glued and coated, removing the rust, dust, greasy dirt and other foreign matter and substance.
  2. Gluing: cutting nozzle to the required angle, extruding the liquid cement to the cleaned surface and making it well-distributed, then folding and fixing the glued surfaces.
  3. Curing: placing the glued or sealed components in the air to make them cured naturally. Curing is a process that being cured from surface to the internal.The sealant will be cured at a depth of 2~4mm within 24 hours (at room temperature and 55% relative humidity), if the glue position is deeper, especially the parts that not easy to come into the air,the time that being completely cured will be longer, if the temperature is low, the curing time will also be extended. It will take more than 7 days to make 6 mm thick sealant fully cured


  1. Tightening and sealing the leftover sealant after the operation.      
  2. Removing the cured cement at the sealing part that might happen during the   preservation, it could be normally used again.
