Product Overview
Our Electronic Potting Compound is specially developed for Free-Space Optical Links, dedicated to encapsulating, sealing, waterproofing and insulating its core electronic components, optical transceiver modules, signal processing boards and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for free-space optical communication scenarios, enhancing high transparency and low light scattering to adapt to the high-speed, low-loss requirements of optical signal transmission. Compared with epoxy potting resin, it has better flexibility, minimal volatile content and excellent environmental adaptability, supports fast curing, and ensures long-term reliable protection for optical components, reducing failure rates and maintenance costs for communication equipment manufacturers.
Key Features & Advantages
- Ultra-High Transparency & Low Light Loss: Optimized formula with ultra-high light transmittance (≥96% at 850/1310nm) and minimal light scattering, ensuring unobstructed optical signal transmission, reducing signal loss and guaranteeing communication stability of free-space optical links.
- Excellent Environmental Adaptability: Stable operation from -60℃ to 220℃, with IP67-level waterproof, dust-proof and anti-ozone performance, resisting outdoor rain, humidity and temperature changes, adapting to outdoor free-space optical communication environments.
- High Insulation & Strong Adhesion: High volume resistivity (≥1.0×10¹⁶ Ω·cm), excellent dielectric strength (≥25 kV/mm), isolating external electromagnetic interference; strong adhesion to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), ensuring tight sealing and structural stability in long-term outdoor operation.
- Low Viscosity & Flexible Curing: Low viscosity, good fluidity, able to penetrate tiny gaps of optical components; addition-curing formula, cures at room or heated temperatures, fully cured in 24 hours, easy to operate and improve production efficiency.
- Low Volatility & Customizability: Minimal volatile content, no harmful substances released, avoiding contamination of optical components; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different free-space optical link equipment models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification that affects transparency and adhesion.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly to ensure full integration without air bubbles that affect light transmission and sealing.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of optical components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature or heat to accelerate, enter the next process after basic curing, and ensure 24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed.
