Electronic Potting Compound

What is electronic potting compound?

Electronic potting compound is a special adhesive for completely encapsulating electronic components and circuits. These materials protect sensitive electronics from moisture, chemicals, mechanical stress and temperature fluctuations.

Properties of electronic potting compounds

  • Low viscosity for complete wetting
  • Excellent dielectric properties
  • Thermal conductivity for heat dissipation
  • Chemical resistance against environmental influences
  • Various hardness levels from flexible to hard

Application areas

  • PCB potting: Protection of SMD components
  • Sensor encapsulation: Protection of pressure sensors and accelerometers
  • Automotive electronics: ECU potting in vehicles
  • LED modules: Protection and optical coupling
  • Medical electronics: Biocompatible encapsulation

Potting processes

  • Vacuum potting: Bubble-free potting under vacuum
  • Pressure potting: Potting under increased pressure
  • Impregnation: Penetration into windings and coils
