Easy-Use Potting Compound HN-8808 - 10:1 Mix Ratio, 60 Min Work Time for Simple Application
Product Overview for Silicone Potting Compound:
We understand that process stability is as important as product performance. The HN-8808 series potting compounds, with their moderate viscosity, generous 40-60 minute pot life, and predictable curing profile, provide ample tolerance for your production process. Easy for both beginners and automated systems to handle, they effectively reduce rejection rates and improve overall production efficiency.
Key Performance Parameters for Silicone Potting Compound:
* Pot Life (25°C): 40-60 minutes – Provides ample working time.
* Viscosity (Mixed): 2000-2600 cP – Good flow for easy filling, yet resistant to spillage.
* Mix Ratio: 10:1 – A forgiving process window, less sensitive to ratio errors, easy to control.
* Curing Profile: Cures at room temperature, no extra equipment needed – Simplifies the process.
* Hardness (Shore A): 30-40 – Moderate elasticity, facilitates subsequent rework.
Product Highlights for Silicone Potting Compound:
* User-Friendly Process Window: Long pot life allows for mixing larger batches or handling complex assemblies, reducing waste.
* Excellent Self-Leveling: Automatically levels and fills fine gaps for a smooth, aesthetic finish.
* Simple Mix Ratio: Easy-to-remember 10:1 weight ratio reduces operator error.
* Clear Cure Indication: Cures from surface inward; skin formation indicates initial cure.
* Convenient Reworkability: Moderate hardness allows for complete removal of cured compound if repair is needed.
Application Areas for Silicone Potting Compound:
* Prototype development and testing
* High-mix, low-volume production
* Factories with lower automation levels
* Educational and DIY electronic projects
* Precision modules where rework is expected
Detailed Operating Guide (Manual Operation Focus) for Silicone Potting Compound:
1. Weighing Tools: Prepare two clean plastic or paper cups and a sufficiently accurate scale.
2. Simple Weighing Method: Place the cup for Component A on the scale and tare. Add 100g of Component A. Then, with the cup still on the scale, tare again. Add 10g of Component B. This avoids container weight error.
3. Manual Mixing Technique: Use a flat-headed stirrer, slowly mixing in a figure-8 pattern while scraping the sides and bottom for a full 3 minutes until completely uniform in color.
4. Simple Degassing: If no vacuum pump is available, let the mixed cup sit for several minutes for large bubbles to rise, and pop surface bubbles with a toothpick or by lightly blowing with hot air.
5. Potting: Pour the compound into one corner, letting it flow and fill naturally. For tall components, consider a two-stage pour: first to 1/2 height, let it gel slightly, then fill completely to prevent bubble entrapment.
Key Precautions for Silicone Potting Compound:
* Ambient Temperature Effect: High summer temperatures shorten pot life; low winter temperatures prolong cure. Adjust work pace accordingly.
* Use Mixed Material Promptly: Use mixed compound within the pot life. Do not return reacting material to the original container.
* Tool Cleaning: Uncured material can be cleaned with alcohol . Once cured, mechanical removal is required.
* Ergonomics: For prolonged use, wear gloves and choose comfortable tools to reduce 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, military), 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.
