Potting and Encapsulating Elastomers

Optically Clear Silicone Elastomer

DESCRIPTION
  • Two-part, optically clear, solvent free, low viscosity silicone
  • Cures at room temperature or rapidly with heat
  • Offers good physical and electrical stability across a broad range of temperatures
  • 1:1 Mix Ratio (Part A:B)
APPLICATION
  • To provide protection of electronic components and assemblies against shock, vibration, moisture, ozone, dust, chemicals and other environmental hazards by potting or encapsulating
  • For photonics applications such as HBLEDs, photo detectors, lasers, discrete optics and flat panel displays that require a1.41 refractive index
