Transparent Potting Silicone Gel HN-6607 | Internal Inspection | High Insulation

Product Overview for Electronic Silicone Gel:

HN-6607 is a high-transparency, two-part silicone gel that remains highly transparent after curing, allowing clear visibility of encapsulated component status and labels. It combines excellent electrical insulation with soft physical properties, making it ideal for applications requiring visual inspection or optical sensing.

Product Performance for Electronic Silicone Gel:

- Appearance: Transparent liquid (A & B Components)

- After Curing: Transparent elastic gel

- Dielectric Properties: Excellent, stable across wide temperature/humidity range

- Hardness After Curing: 0–10 Shore A

Product Highlights for Electronic Silicone Gel:

- ✅ High Clarity: Facilitates visual inspection of internal components and labels.

- ✅ Superior Insulation: Reliable dielectric strength for high-voltage safety.

- ✅ Stress Relief: Soft protects delicate solder joints and leads.

- ✅ Chemical Stability: Resists aging and ozone.

Product Applications for Electronic Silicone Gel:

- Potting modules with LED indicators

- Peripheral sealing for optical sensors and lenses

- Encapsulation where QR codes/barcodes must be visible

- Insulating layers for advanced test fixtures and probe stations

Operation Guide for Electronic Silicone Gel:

1. Ensure Component A and B containers and the working environment are clean and free from contaminants.

2. Mix at 1:1 weight ratio. Stir moderately to avoid excessive air entrapment.

3. After potting, allow to settle or vacuum degas to eliminate bubbles for optimal clarity.

4. Cure at 120°C for 20-30 minutes.

Precautions for Electronic Silicone Gel:

- Contamination can affect transparency and cure performance.

- Control vacuum level and time during degassing to prevent boiling over.

Packaging & Storage for Electronic Silicone Gel:

- Packaging: 40 kg per set (20 kg pail of A + 20 kg pail of B)

- Storage: Keep in a sealed container in a cool, dry place, away from direct sunlight, below 25°C.

- Shelf Life: 6 months (below 25°C).

- Transportation: Classified as non-hazardous goods; can be transported as general chemicals.

FAQ for Electronic Silicone Gel:

1. Q: Will it yellow over time?

A: It offers good yellowing resistance and remains clear under normal indoor conditions. Risk increases under sustained high heat or strong UV exposure.

2. Q: Does transparency compromise protection?

A: Not at all. Transparency is a physical property; its moisture, insulation, and shock resistance remain excellent.

3. Q: Can it be used for potting silicon photocells or optical lenses?

A: Yes, its light transmission and insulation are suitable. For optical performance, test samples to evaluate transmittance and refractive index.

4. Q: How to achieve the best transparency?

A: Key points: ① Use clean containers/tools; ② Avoid introducing bubbles during mixing; ③ Allow settling or vacuum degas after potting.

5. Q: What are its advantages vs. transparent epoxy?

A: Compared to epoxy, HN-6607 is softer, offers better stress relief and thermal shock resistance (-50°C to 150°C), with very low curing stress.
