CHT Group QSil 12 Translucent Silicone Potting Compound

Description

QSil 12 silicone is a clear, low-viscosity, two-component silicone potting compound from CHT Group. Chemical Concepts product context describes it as a 100:5 mix material for room-temperature cure, with self-leveling flow, about two hours of work life after mixing, and full cure in 24 to 48 hours at room temperature.

QSil 12 silicone Applications

• Potting electronic assemblies that need a clear protective silicone.
• LED and electrical work where low-viscosity flow helps fill small spaces.
• Encapsulation of components where visual inspection through the material is useful.
• Prototype and production jobs that need room-temperature cure.
• Workflows that may use mild heat to reduce cure time after qualification.

This product is primarily positioned for potting rather than general-purpose bonding. The material should be selected based on electrical, optical, cure, and handling requirements, not only on package size. Confirm the current technical data sheet before changing mix method, cure temperature, or primer use.

QSil 12 silicone Benefits

• Clear cured appearance supports inspection of embedded parts and wiring.
• Low viscosity helps the material flow into detailed assemblies.
• Self-leveling behavior supports clean potting surfaces when fixtures are level.
• Room-temperature cure fits many electronics processes without oven exposure.
• 100:5 mix ratio gives a defined process target for production documentation.

Mixing and Handling Notes

Measure the base and catalyst accurately, then mix until the batch is uniform. Avoid contamination from old silicone, oils, dust, or incompatible cleaners. Degas when the assembly or quality requirement calls for it. Pour slowly so air can escape from corners and under components, then protect the assembly from movement while the silicone cures.
