Product description of epoxy potting compound

SATOP®8613A/B is a two-component solvent heating type epoxy potting compound,It is suitable for packaging and protection of products with high thermal conductivity requirements in motors, automotive electronics, power tools, reactors, and meters, and has excellent adhesion and temperature resistance.

  • Excellent adhesion and crack resistance
  • Low CTE linear expansion coefficient
  • High thermal conductivity
  • Excellent electrical insulation and stability
  • Long-term use at 150°C-180°C
  • Very low water absorption, good water and moisture resistance

Operation process of epoxy potting compound

  • PartA will settle in the storage process, first mix Part A in the original package, and then add Part A and Part B components by a weight ratio of 5:1. Potting.
  • component may crystallize or agglomerate (normal condition) during storage.If crystallized, need to be placed in an oven at 80°C to melt before use(the container should be open to avoid gas expansion and damage the container), and then used after being cooled to room temperature, this does not affect its performance.
  • B component is exposed in the air and hydrolysis occurs with the moisture reaction, and the hydrolyzedproduct is white powder. When weighing, avoid the white stuff.
  • If necessary, the potted device can continue to be vacuumed, which is beneficial to increase the electrical performance of the device.
  • 25°C*24 hours. For better performance, follow the 100°C*2 hour or 80°C*3 hour curing process.

Storage and transportation

  • A, B components need to be protected from light, heat, sealed and stored (can be transported and stored as non-dangerous goods);
  • The storage period is one year.


  • Part A:20kg/plastic barrel; Part B: 8kg or 2.4kg/pot
