Silicone Potting Compound HN-8806 – 0.76 W/m·K, 1:1 Mix Ratio, RTV Addition Cure

Typical Applications

HN-8806 is widely used in:

• Power Modules & Inverters

• High-Voltage Transformers

• Battery Packs & EV Chargers

• LED Outdoor Drive Power Supplies

• Fast-Charging Adapters

• Automotive Control Units

• Network & Communication Devices

Handling & Curing Instructions

1. Preparation – Stir Components A and B separately before use.

2. Weighing – Weigh A and B in a 1:1 ratio.

3. Mixing – Mix thoroughly in a clean container. Stir in one direction to minimize bubbles.

4. Degassing – Vacuum degas for 5–10 minutes if required.

5. Potting – Pour into clean, dry housings. For large parts, consider staged potting.

6. Curing – Cure at room temperature (4–12 hrs) or heat at 80°C for 0.2 hrs.

Important Notes

• Store sealed in a cool, dry place. Shelf life: 6 months.

• Avoid contact with tin, sulfur, amine, phosphorus, or heavy metals – they inhibit curing.

• Do not mix with condensation silicones, epoxy, or polyurethane.

• Stir evenly to avoid partial non-curing.

• Vacuum degassing after potting can improve thermal performance.
