Description
The CHT QGel 313 is a clear, two-part silicone encapsulant gel that cures to a soft, tough, moderately cross-linked cushion for protecting sensitive electronics. It pots delicate assemblies in a low-stress gel that absorbs shock and vibration, seals out moisture, and stays soft enough to rework or probe after cure. A wide work life and simple hand mixing make it practical for low-volume and repair work.
Where the QGel 313 Encapsulant Is Used
Electronics builders use this gel to pot sensors, circuit assemblies, LED work, and low-voltage components that cannot take the stress of a rigid potting compound. The clear cured gel lets a technician see and reach the components underneath, which helps with inspection, troubleshooting, and rework. Because it needs no dispensing equipment, a shop can mix and pour small batches by hand.
How the Encapsulant Performs
Two mix ratios set the final hardness: a 20 to 1 blend by weight or volume gives the standard soft gel, and a 10 to 1 blend yields a firmer set. Work life runs beyond seven days at room temperature, so mixed material stays usable across a long session, and a heat step drives the final cure. The result is a stable, low-stress silicone cushion around the parts.
