Description
QGel 920 silicone gel is a clear, high refractive index phenyl silicone gel from CHT Group for optical and electronic encapsulation work. The product data lists a 1:1 mix ratio by weight, transparent color, addition-cure chemistry, and room-temperature cure option for assemblies that need flexible protection without a hard potting compound.
QGel 920 silicone gel Applications
This gel fits LED modules, optical transmission assemblies, sensors, connectors, and electronics that need moisture protection, vibration damping, and shock isolation. Its soft cured profile helps protect delicate components from thermal or mechanical movement, while the clear appearance lets technicians inspect the covered area after cure. Use it where a rigid epoxy would put too much stress into components or make rework too destructive.
QGel 920 silicone gel Process Notes
- Mix part A and part B at 1:1 by weight using clean containers and dry tools.
- Use matching lots when the data sheet requires paired material for best performance.
- Apply QSil Primer 5 when the job requires stronger adhesion to the substrate.
- Plan around the listed 120 minute gel time at 25 C for bench work.
- Store below the published maximum storage temperature and check shelf life before use.
Technical Fit
CHT data identifies this material as a moderately cross-linked silicone polymeric elastomer with protection against moisture, vibration, thermal shock, and mechanical shock. Cure options include 24 hours at 25 C, 60 minutes at 100 C, or 30 minutes at 150 C, so process teams can choose a schedule based on the assembly temperature limit. The soft gel body can also support service work where later access to covered parts matters. For related products, browse Chemical Concepts encapsulants and potting compounds.
