R-2188

SILICONE POTTING AND ENCAPSULATING ELASTOMER

 

Description

  • Two part, Clear, 1:1 Mix ratio (A:B)
  • Pourable and self-leveling
  • Cures at room temperature
  • REACh and RoHS compliant
  • Tested per UL-94 and passed V-1

Applications

  • For potting, encapsulating and coating of modules, relays, and a variety of AC/DC converters including high power and planar packages
  • Provides protection from moisture, dust and contaminants
  • Increases resistance to shock and vibration
  • Low viscosity allows the potting of complex geometries without the entrapment of air
  • Pot life is compatible with processes that require dispensing or coating with Part A and B combined
  • Dielectric properties compatible with many devices and increase breakdown voltage of device
