Optically Clear Silicone Gel
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
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
Viscosity (initial Part A and Part B mixed) 360 cP
Viscosity at 3 hours after catalyzation < 4,000 cP
Cured: 30 minutes at 150°C (302°F)
Durometer, Type 00 25
Specific Gravity 1.07
Refractive Index, 589 nm 1.52
Moisture Absorption, % gain after 168 hour exposure at 85°C (185°F) / 85% R.H. < 0.2 %
Cured: 24 hours at ambient temperature and humidity Durometer, Type 000 65

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.
