LightSpan® LS1-3252 | África & Oriente Médio |
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
