Soft Gel; Excellent for phosphor coatings.


  • High purity, optically clear, soft silicone gel
  • Medium viscosity components can be blended in a convenient 1:1 ratio by weight or volume
  • Cures at room temperature in 24 hours
  • 1.54 refractive index
  • Good UV Resistance
  • Good adhesion without the use of primer


  • For potting, encapsulating, backfilling, and dampening applications requiring a soft gel with optical clarity
  • Viscosity makes excellent for dispersing phosphors to obtain high brightness white light
  • For applications requiring an operating temperature range of -40°C to 200°C (-40°F to 392°F) or for soldering operations up to 260°C (500°F) for 1 to 2 minutes
