Product feature and application

SATOP®8125 A/B is a two component Condensation type silicone potting compound for electronics components. It can be deeply solidified, have good fluidity after mixing, and operation time can be adjusted according to temperature adjustment curing agent.  Don’t need primer before use, have good adhesion effect to most materials, suitable for fixed and waterproof, dustproof and anti – leakage.

  1. Two components, condensed and dehydrogenated.
  2. Low viscosity, easy to process, good
  3. Low hardening shrinkage, no corrosion and no stress.
  4. Excellent high temperature electrical insulation and stability.
  5. Excellent adhesion, good waterproof, moisture proof.

How to use of silicone potting compound for electronics

  • 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 is possible to vacuumize the mixture before pouring. Or solidified directly at room temperature, which requires about 1-6hr.



Part A: 20kg/barrel;  Part B: 5kg/pot

Part A: 200kg/barrel; Part B: 20kg/pot

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)
