Potting and Encapsulating Elastomers

Optical Thermoset

DESCRIPTION
  • Two-part, optically clear silicone system
  • Based on a methyl silicone polymer
  • Low viscosity
  • 1:1 Mix Ratio (Part A:B)
APPLICATION
  • For bonding, casting or injection molding of high performance optical components
  • For applications requiring index matching at 1.40
  • For photonics applications requiring low outgassing and minimal volatile condensables to avoid condensation in sensitive devices
