LS1-3252

Gels

Optically Clear Silicone Gel

DESCRIPTION
  • Two-part, 1:1 Mix Ratio (Part A: Part B)
  • 1.52 refractive index for matching BK7
  • Cures with heat via addition-cure chemistry and will cure at room temperature
APPLICATION
  • For protection of sensitive photonics assemblies from mechanical shock, thermal shock, dust, and ambient atmosphere.
  • Low viscosity reduces 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 optically clear materials with a refractive index of 1.52 at 589 nm
  • For LEDs and display assembly

Recommended Primers CF2-135 - SP-120 - SP-271

Note: Some bonding applications may require the use of a primer.
CF2-135 is recommended for most metallic substrates, some plastics and when cure inhibition is observed on substrate.
SP-120 is recommended for PPA and SP-271 is recommended for PMMA.
