Description
The CHT QGel 312 encapsulant is a clear silicone gel for electronics assemblies that need soft protection from vibration, moisture, and thermal or mechanical shock. It cures into a resilient, moderately cross-linked silicone polymer rather than a hard plastic mass, so it can cushion sensitive components while still filling the cavity around them. The 10:1 mix ratio supports controlled dispensing, and the material can cure at room temperature over 24 hours or with heat when the process needs faster throughput.
Where this encapsulant fits
QGel 312 fits LED modules, electronic packages, sensor housings, and component cavities where stress relief matters as much as environmental protection. Silicone gel is useful around fine wires, solder joints, small board-mounted components, and delicate assemblies that might be damaged by a rigid potting compound. The clear cured appearance lets technicians inspect part placement, air pockets, and the general condition of the assembly after filling, which can be valuable during process qualification or repair analysis.
The material can be hand mixed for development work because dedicated dispensing equipment is not required. For repeat production, metered 10:1 dispensing improves ratio control and keeps fill volume consistent from part to part. Before production use, qualify the surface, cavity depth, cure schedule, and any thermal limits on the device. Parts should be clean, dry, and staged in a fixture that prevents movement while the gel levels and cures.
How QGel 312 protects components
A soft silicone gel helps absorb movement instead of transferring all stress into the component body or solder joint. That makes it useful when the assembly may see vibration, handling shock, or repeated temperature change. The gel fills the open space around parts and helps block moisture paths, while the clear material keeps the assembly readable after cure. Because the product has both room-temperature and heat-cure options, a shop can choose slower cure for low-volume builds or add heat when the parts and fixture can tolerate it.
