  • Part A: 20kg/barrel. Part B, 20kg/barrel
  • Part A: 200kg/barrel. Part B, 200kg/barrel

Storage and transportation

  • 1 Part A and part B need to avoid light, heat, save after sealed. (Can be used as the non-dangerous goods transport and storage)
  • Shelf life : 1 years (25℃)
  • For a long period of time, there will be precipitation, which can be used after stirring. This phenomenon is not a quality problem.

Application of potting compound:

  1. Automotive electronics, modules.
  2. LED power driver module.
  3. Solar module junction box.
  4. Electric vehicle charging column module.
  5. Lithium battery and capacitor bank.
  6. Magnetic induction coil
  7. power inverters

 How to use of potting compound

  • The glue will cause precipitation if placed too long, mix part A and part B in each package before construction.
  • Weigh part A and part B by 1:1, mix well, direct injection into components (or modules). It is best to gently inject into the side of the wall to reduce the bubble formation.
  • Put the encapsulated element in place for some time. After the bubble disappears, it can be heated and solidified, or solidified directly at room temperature, which requires about 4hr.
