Description
CHT TufGel 330 Silicone Gel 8 lb Kit is a two-part potting and encapsulating material built for electronics that need cushioning from vibration, thermal cycling, and moisture. It mixes 1:1, cures at room temperature or with heat, and is supplied in a bulk kit that can be staged for bench work or repeated plant maintenance jobs.
TufGel 330 silicone gel Benefits
- Low viscosity around 700 to 800 cP helps the gel flow around components and connectors with less trapped air.
- Firm Shore 00 hardness supports cushioning without putting heavy stress on delicate assemblies.
- Transparent appearance makes visual inspection easier after cure.
- Service range from -55 C to 204 C supports electronics exposed to wide thermal swings.
- Inherent tack and primer-assisted adhesion help the gel stay in place on glass, aluminum, and copper details.
This material is positioned for encapsulation and protection of electronic components. CHT lists protection from vibration, thermal or mechanical shock, water, and environmental contaminants, which makes it a practical choice for control boxes, lighting assemblies, sensors, and other parts that need a soft gel instead of a rigid potting compound.
Common Applications for TufGel 330 silicone gel
- Potting and encapsulating electronic components.
- Moisture protection for assemblies exposed to washdown or outdoor humidity.
- Shock damping around connectors, relays, and small control hardware.
- Bench repairs where a removable or repairable gel is preferred over a hard resin.
Compatible Materials
- Glass, copper, and aluminum with the recommended primer step.
- Electronic housings and assemblies that benefit from a soft, adherent silicone gel.
- Bulk dispensing setups where powered equipment is not required.
