Description
CHT Group QGel 910 is a QGel 910 silicone gel for transparent encapsulation and optical applications that benefit from a high refractive index. This phenyl gel mixes 1:1 by weight, cures by addition chemistry, and stays soft while providing a clear protective fill around sensitive parts.
QGel 910 Silicone Gel Benefits
- High refractive index of 1.47 supports optical and display-related gel applications.
- Transparent cured gel helps preserve visual access to the protected assembly.
- 1:1 mix ratio supports hand mixing or controlled dispensing setup.
- Soft but resilient gel helps reduce stress from vibration, thermal cycling, and movement.
- Good adhesion with QSil Primer #5 is listed for jobs that need stronger chemical adhesion.
Use this material when optical clarity, soft stress relief, and moisture protection must be balanced in one gel system. It can fill LED, sensor, display, and electronic cavities where a rigid encapsulant would be too stiff. Run trials on the exact optical stack and housing because layer thickness, trapped air, surface cleanliness, and cure temperature can affect final appearance.
Common Applications for QGel 910 Silicone Gel
- Optical bonding and transparent electronic encapsulation.
- LED, sensor, and display assemblies that need a clear gel layer.
- Soft fill around delicate components exposed to vibration or thermal cycling.
- Electronic housings that need a low-modulus protective material.
- Assemblies where primer-assisted adhesion is part of the process plan.
Compatible Materials and Handling Notes
- Use on clean glass, plastic, metal, or electronic surfaces after a compatibility test.
- Control mix quality and air release carefully for clear or optical builds.
- Use QSil Primer #5 only where the process calls for stronger adhesion.
- Confirm cure and appearance on sample parts before approving production work.
