Product Overview
Our Electronic Potting Compound is specially developed for Adaptive Optics Systems, dedicated to encapsulating, sealing, insulating and protecting deformable mirrors, wavefront sensors, control modules, PCB substrates, and precision optical electronic components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for high-precision optical scenarios, enhancing low signal interference, high stability and environmental adaptability to adapt to the extreme precision, low-noise operation requirements of adaptive optics systems. Compared with epoxy potting resin, it has minimal volatile content, no exotherm during curing, low shrinkage, and absorbs thermal stress, ensuring long-term reliable operation of components in telescopes, aerospace, medical imaging and laser communication fields.
Key Features & Advantages
- Ultra-Low Signal Interference: Optimized formula with ultra-low dielectric loss and minimal electromagnetic interference, avoiding interference with adaptive optics wavefront signals and sensor operation, ensuring high-precision optical correction and stable signal transmission (critical for adaptive optics performance).
- Superior Stability & Temperature Adaptability: Stable performance from -60℃ to 220℃, withstanding minimal temperature fluctuations; effectively absorbing thermal stress generated by component operation, avoiding deformation of precision optical parts and ensuring consistent optical correction accuracy.
- High Insulation & Purity: High volume resistivity (≥1.0×10¹⁶ Ω·cm), excellent dielectric strength, isolating internal and external static and interference; minimal volatile content, no harmful residues, ensuring the cleanliness of internal precision optical electronic components.
- Precision Curing & Easy Operation: Adjustable weight mixing ratio, easy to proportion and stir; curable at room or heated temperatures, fully cured in 24 hours; optional vacuum degassing (0.01MPa for 3 minutes) to eliminate air bubbles, ensuring full penetration into tiny gaps of precision components without affecting optical performance.
- Strong Adhesion & Customizability: Excellent adhesion to PC, PMMA, PCB, aluminum, copper and stainless steel, ensuring tight sealing of adaptive optics components; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and interference resistance to match different adaptive optics system 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 insulation and signal interference performance.
- 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 cause signal distortion and affect optical correction precision.
- 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 adaptive optics precision 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.
