* E-bike controllers, chargers

* Outdoor electronics (benefiting from its weather resistance)

Detailed Operating Guide for Silicone Potting Compound:

1. Surface Preparation: Ensure surfaces are free of dust, oil, release agents, etc., to prevent affecting adhesion and appearance.

2. Pre-use Stirring: Stir Component A until fillers are uniformly dispersed before use. This is the crucial first step for consistent color and performance.

3. Accurate Weighing: Use an electronic scale to weigh Components A and B precisely at a 10:1 weight ratio. Deviation can lead to incomplete curing or property loss.

4. Thorough Mixing: Mix slowly in a clean container for at least 3 minutes, scraping sides and bottom, until color is uniform without streaks.

5. Vacuum Degassing: Degas the mixed compound under vacuum for 2-4 minutes until no large bubbles remain on the surface. This ensures a smooth, aesthetic surface finish.

6. Potting and Curing: Pour the compound slowly into the device, allowing it to self-level. Cure at 25°C. Light handling is possible after 24 hours; optimal performance is reached after 7 days.

Key Precautions for Silicone Potting Compound:

* Color Consistency: Filler settling in Component A causes uneven color. Must stir thoroughly before use.

* Contamination Control: Mixing and potting tools must be clean; any impurities will be very visible in the white compound.

* Do Not Heat Cure: Heating is prohibited as it causes foaming and discoloration, affecting appearance and performance.

* Controlled Environment: The curing environment should be clean to prevent dust from settling on the uncured surface.

Packaging & Storage for Silicone Potting Compound:

* Standard Packaging: 22kg/set (20kg A + 2kg B); 11kg/set (10kg A + 1kg B).

* Storage Conditions: Store in a cool, dry place away from direct sunlight.

* Shelf Life: 6 months in original, unopened containers from date of manufacture.

FAQ for Silicone Potting Compound:

1. Q: Under what conditions might the white compound yellow?

A: Prolonged exposure to strong UV (direct sunlight) and continuous high temperatures (near 200°C) accelerates yellowing. Our optimized formulation offers superior yellowing resistance compared to standard market products.

2. Q: How do you ensure consistent color between batches?

A: We employ strict raw material control and automated production, ensuring batch-to-batch color stability. We recommend checking a sample before mass production.

3. Q: Is the white version's thermal conductivity the same as the black?

A: Yes, both HN-8808W and HN-8808B have a thermal conductivity of 0.5±0.1 W/M·K. The white version uses special fillers to achieve heat dissipation equal to the black version.

4. Q: Can I use the white compound if my product housing is transparent?

A: Yes, but it will completely obscure internal components. If visual inspection is needed, you should choose the HN-8808A/B Transparent version.

5. Q: Can you customize other colors?

A: Yes. We support color customization (e.g., gray, blue) to meet your brand identification needs. Please consult our sales for MOQ.
