Two-Part Silicone Potting Compound HN-8808 - 10:1 Ratio for Electronics Encapsulation

Two-Part Silicone Potting Compound HN-8808 - 10:1 Ratio for Electronics Encapsulation

Product Overview for Silicone Potting Compound:

The HN-8808 is a two-component, condensation-cure RTV (Room Temperature Vulcanizing) silicone rubber potting compound. Designed for ease of use and reliable performance, it cures at room temperature to form a durable, flexible elastomer after mixing Components A and B at a straightforward 10:1 weight ratio. It provides essential protection for electronic assemblies against moisture, dust, thermal cycling, and mechanical stress, ensuring long-term reliability across a wide range of applications.

Key Performance Parameters for Silicone Potting Compound:

* Chemistry: Condensation Cure Silicone Rubber

* Mix Ratio (A:B): 10 : 1 (by weight)

* Pot Life (25°C): 40-60 minutes

* Cure Time (25°C): 4-6 hours (tack-free), 24 hours (full cure)

* Hardness (Shore A): 30-40

* Temperature Range: -50°C ~ 200°C

* Volume Resistivity: ≥5.0×10¹⁴ Ω·cm (Transparent: >4.0×10¹⁴)

* Dielectric Strength: ≥14 kV/mm

* Thermal Conductivity: 0.3 W/M·K (Transparent) / 0.5 W/M·K (Black/White)

Product Highlights for Silicone Potting Compound:

* Simple 10:1 Mix Ratio: Easy to remember and measure, reducing potential for mixing errors.

* Room Temperature Cure: No oven or external heat source required, saving energy and simplifying process.

* Versatile Protection: Offers a balanced combination of electrical insulation, environmental sealing, and shock absorption.

* Flexible & Durable Elastomer: Absorbs stress from thermal expansion and vibration, protecting delicate components.

* Multiple Color Options: Available in Transparent, Black, and White to meet different application needs.

Application Areas for Silicone Potting Compound:

* General electronic control module potting

* Sensor encapsulation

* Power supply components

* Automotive electronics (non-safety critical)

* Consumer appliance boards

* LED modules

Detailed Operating Guide for Silicone Potting Compound:

1. Preparation: Ensure components and housing are clean and dry. Stir Component A thoroughly before use.

2. Weighing: Accurately weigh Components A and B onto a scale using the 10:1 weight ratio.

3. Mixing: Combine both parts in a clean container. Mix vigorously for 2-3 minutes until the color is completely uniform, scraping sides and bottom.

4. Degassing: For best results, especially with deep fills, degas the mixed material under vacuum until bubbling stops.

5. Potting: Pour or dispense the material into the assembly. It will self-level to cover components.

6. Curing: Allow to cure undisturbed at room temperature (25°C). Handling strength is achieved in 4-6 hours.

Key Precautions for Silicone Potting Compound:

* Accurate Ratio: Do not deviate from the 10:1 mixing ratio. Inaccurate ratios prevent proper curing.

* Complete Mixing: Inadequate mixing results in uncured spots and poor performance.

* No Heat Cure: This is a condensation cure system. Applying heat will cause bubbling and prevent proper curing.

* Ventilation: Ensure adequate ventilation during potting and initial cure.

Packaging & Storage for Silicone Potting Compound:

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

* Storage Conditions: Keep in original, tightly sealed containers in a cool, dry place (10-30°C).

* Shelf Life: 6 months from manufacture date.

FAQ for Silicone Potting Compound:

1. Q: What is the difference between the transparent, black, and white versions?

A: The primary differences are thermal conductivity (Transparent: 0.3, B/W: 0.5 W/M·K) and optical properties. Black offers some EMI shielding, White is aesthetic/reflective, Transparent allows visual inspection.

2. Q: Can I use volume instead of weight for measuring?

A: No. Due to density differences, the volume ratio is not 10:1. Always use weight for accuracy.

3. Q: Is it suitable for outdoor use?

A: Yes, its silicone base provides excellent resistance to weathering, ozone, and UV radiation (especially black and white).

4. Q: How do I remove cured silicone for repairs?

A: The cured rubber can be cut and peeled mechanically. It is challenging but possible without damaging components if done carefully.

5. Q: What is the minimum order quantity?

A: Our standard MOQ is one 11kg kit. Contact us for smaller trial orders.
