ULTRA-CLEAR ENCAPSULATION GEL, PRELIMINARY DATA

 

Description

  • A two-part, encapsulation gel
  • Extended work time
  • 1.46 refractive index for matching silica
  • 1:1 Mix Ratio (Part A:B)

Applications

  • For protection of sensitive photonics assemblies from mechanical shock, thermal shock, dust, and ambient atmosphere
  • Extended work time allows voids in complex assemblies to fill in and permits time for any trapped air bubbles to float to the fluid surface and escape
  • 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
