Description
CHT Silicone Electronics Gel is a transparent two-part silicone electronics gel for encapsulation and potting work. QGel 900 has a 1:1 mix ratio, soft resilient gel form, and published high refractive index profile for assemblies that need flexible protection around sensitive components.
QGel 900 Benefits
- Transparent gel supports optical and inspection-sensitive electronics assemblies.
- 1:1 mix ratio helps simplify hand mixing, meter mixing, and small-batch preparation.
- Soft cured gel helps isolate delicate devices from vibration, shock, and movement.
- Published low temperature and high refractive index positioning helps engineers compare it with other QGel grades.
- Room temperature and heat cure profiles give process teams options for different production schedules.
Silicone gels are chosen when a hard potting compound would place too much stress on components or make later inspection difficult. This grade is a fit for LED, optical, sensor, and electronics work where the gel needs to remain flexible after cure. Use the technical data sheet to confirm pot life, cure schedule, temperature exposure, and primer requirements before releasing a production build.
Common Applications
- Encapsulation of delicate electronics and assemblies.
- Optical transmission applications that require a transparent silicone gel.
- Moisture protection around sensors, connectors, and electronic modules.
- Low temperature service where a flexible silicone gel is preferred over a rigid potting compound.
Compatible Materials and Processing
- Two-part addition cure silicone processing.
- Manual mixing when batch size and process controls allow it.
- Primer-assisted adhesion where the CHT data recommends QSil Primer #5.
- Dispensing equipment selected for a 1:1 silicone gel system when production volume requires it.
