LS-6143

OPTICAL THERMOSET

 

Description

  • Two-part, low viscosity clear RTV silicone
  • Based on a dimethyl-diphenyl copolymer with a broad operating temperature range
  • 10:1 Mix Ratio (Part A:B)

Applications

  • For bonding, casting or injection molding of high performance optical components
  • For applications requiring index matching at 1.43
  • For photonics applications requiring low outgassing and minimal volatile condensables to avoid condensation in sensitive devices
  • For applications requiring an operating temperature range of -115°C to 260°C (-178°F to 500°F)
