Product Specification

Vibration Resistant Soft Silicone Potting Compound For Outdoor High Power LED Driving Units

Product Overview for Silicone Potting Compound:

We recognize process stability equals product reliability. HN-8808 potting compounds feature moderate viscosity and a 40–60 minute workable pot life, along with consistent curing performance, bringing great flexibility to your production. Easy to use for manual operation and automated lines alike, they help cut defect rates and boost production efficiency.

Key Performance Parameters for Silicone Potting Compound:

• 25°C Pot Life: 40-60 min | Enough time for operation
• Mixed Viscosity: 2000-2600 cP | Smooth flow, no leakage
• Mix Ratio 10:1 | High fault tolerance, simple to control
• Room temperature curing | No additional equipment needed
• Shore A 30-40 | Flexible texture, easy rework

Product Highlights for Silicone Potting Compound:

• Wide Process Latitude: Extended pot life supports large-batch mixing and complex assembly work, minimizing material waste.
• Superior Self-Leveling: Spreads evenly and fills tiny gaps, delivering a neat surface finish.
• Simple Mix Proportion: Easy-to-follow 10:1 weight ratio effectively lowers operating errors.
• Visible Curing Status: Cures gradually from the surface inward; skin formation marks the initial curing stage.
• Easy Rework: Moderate hardness enables full removal of cured material for maintenance and repairs.

Application Areas for Silicone Potting Compound:

• Suitable for prototype development and testing
• Fits high-mix, low-volume production scenarios
• Works well in low-automation production lines
• Ideal for electronic teaching and DIY projects
• Perfect for precision modules with rework demands

Detailed Operating Guide (Manual Operation Focus) for Silicone Potting Compound:

•  Prepare clean cups and precise weighing tools before use
•  Tare scale twice when dosing A and B to rule out container weight errors
•  Stir thoroughly for 3 minutes in figure-eight motion for uniform mixing
•  Let mixture stand to release bubbles; clear surface bubbles manually if no vacuum pump
•  Pour from one corner. Use two-stage pouring for tall components to avoid trapped air​

Key Precautions for Silicone Potting Compound:

• Ambient Temperature: High temperatures in summer shorten pot life, while low temperatures in winter slow down curing. Please adjust your working pace accordingly.
• Material Usage: Use the mixed compound within its pot life. Do not put reacting material back into original containers.
• Tool Maintenance: Clean uncured material with alcohol. Cured material can only be removed mechanically.
• Safety & Comfort: Wear gloves and use ergonomic tools for long-time operation to relieve fatigue.

Packaging & Storage for Silicone Potting Compound:

• Standard Packaging: 22kg/set; 11kg/set. Smaller packages suit flexible production needs.
• Storage Conditions: Store in a cool, dry place.
• Shelf Life: 6 months in original, unopened containers from date of manufacture.

FAQ for Silicone Potting Compound:

1. Q: The 40-minute pot life starts from when?

A: It starts from the moment Components A and B begin mixing. We recommend completing mixing, degassing, and pouring within 30 minutes, leaving a 10-minute safety margin.

2. Q: What if I accidentally get the ratio wrong, say 11:1?

A: The 10:1 ratio has some tolerance. 11:1 (excess A) may lead to incomplete cure and internal softness. 12:1 carries higher risk. Keep error within ±5%.

3. Q: How critical is a vacuum pump for performance?

A: For most consumer-grade products, sitting and manual bubble removal yields acceptable performance. For high-reliability (auto), vacuum degassing is essential.

4. Q: How to clean glue from skin?

A: Uncured, wipe off most with a paper towel, then wash with soapy water or alcohol. Cured silicone is insoluble and will wear off naturally; don't worry.

5. Q: Do you offer small trial kits?

A: Yes. We offer 1kg trial kits (909g A + 91g B) for process validation and performance testing. Feel free to apply.
