Potting and Encapsulating Elastomers

THERMALLY CONDUCTIVE SILICONE POTTING ELASTOMER

DESCRIPTION
  • Two part, Black, 1:1 Mix ratio (A:B)
  • Pourable and self-leveling
  • Cures at room temperature
  • Tested per UL-94 and passed V-0
APPLICATION
  • Thermally stable, flowable material that cures at room temperature
  • Low viscosity allows the potting of complex geometries without the entrapment of air
  • Quick set-up and flexible cure schedule
  • Applications include: potting for connectors, sensors, relays, power devices and other electronic components requiring protection from vibration and generally harsh environmental conditions
