UV Resistance 10:1 Clear Silicon Potting Compound For LED Drivers, Flexible Light Strips
UV Resistance 10:1 Clear Silicon Potting Compound For LED Drivers, Flexible Light Strips
Product Overview for Silicone Potting Compound:
10:1 transparent silicone potting compounds—typically of the addition-curing (platinum-catalyzed) or neutral de-alcohol condensation type—command distinct high-end application scenarios within industrial manufacturing, thanks to their exceptional transparency (characterized by high light transmittance), superior resistance to yellowing, and stable physicochemical properties.
Key Performance Parameters for Silicone Potting Compound:
- Thermal Performance: Superior resistance and moisture-proof integrity from -57°C to 250°C.
- Dielectric Stability: Non-corrosive addition-cure formulation with zero chemical byproducts; preserves high dielectric strength under extreme stress.
- Material Safety: 100% non-toxic, odorless, and resistant to swelling or chemical degradation.
- Excellent Adhesion: Secure, primerless bonding to metals (aluminum, iron) and engineering plastics (acrylic, PC).
- Stress Relief: Low-viscosity compound cures into a soft, flexible rubber that effectively absorbs impact, vibration, and thermal expansion
Application Areas for Silicone Potting Compound:
Automotive & Aerospace Displays
Optical Instruments & Precision Sensors
Solar Photovoltaic & Green Energy
LED Lighting & Display Systems
Detailed Operating Guide (Manual Operation Focus) for Silicone Potting Compound:
- Dosage & Ratio Optimization: Based on the required potting volume, compound Parts A and B at a base ratio of 10:1 (A:B). This proprietary formula allows for a flexible curing profile; adjusting the dosage by increasing Component B will systematically decrease the tack-free and full-cure times to match fast-paced production lines.
- Dispensing & De-airing: Mix thoroughly in a dedicated clean vessel until completely uniform, then pour smoothly into the target mold or electronic housing. For applications demanding optical clarity or high insulation stability, execute a brief vacuum-de-airing cycle to remove any lingering air pockets prior to the gelation phase.
- Curing Mechanism: The mixture undergoes a reliable cross-linking process at ambient room temperature, transforming into a low-stress, high-performance soft rubber without shrinking or releasing heat.
Packaging for Silicone Potting Compound:
* Standard Packaging: 22kg/set; 11kg/set. Smaller packages suit flexible production needs.
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.
