HONG YE SILICONE Electronic Potting Silicone for Deep Space Transponders is a space-grade two-component Addition Curing Silicone, also known as Electronic Potting Compound and Silicone Encapsulant, tailored for deep space transponder equipment. Crafted from high-purity Silicone raw materials, it integrates vacuum compatibility, anti-cosmic radiation, ultra-low signal interference, wide temperature adaptability and low volatility. After mixing with curing agent, it cures into a solid protective layer, with strong adhesion to PC, PMMA, PCB and aerospace-grade metals, protecting core transponder components, ensuring stable signal transmission in deep space, and supporting full parameter customization to meet global aerospace procurement demands (around 196 characters).
Product Overview
Our Electronic Potting Silicone is specially developed for deep space transponders, dedicated to encapsulating, sealing, filling and protecting their core electronic components, signal transmission modules, antenna interfaces and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for deep space environments, enhancing vacuum compatibility and anti-cosmic radiation performance to adapt to extreme conditions like ultra-high vacuum, intense radiation and large temperature differences. Compared with epoxy potting resin, it has better flexibility and stress absorption capacity, supports room-temperature or heated curing, and ensures long-term reliable protection for transponder components, reducing space mission failure risks and maintenance costs for aerospace manufacturers.
Key Features & Advantages
- Excellent Vacuum Compatibility: Ultra-low outgassing rate, no volatile substances released in ultra-high vacuum environments, avoiding contamination of transponder components and ensuring stable operation in deep space.
- Anti-Cosmic Radiation Performance: Optimized formula resistant to cosmic ray and ionizing radiation, avoiding material degradation and insulation failure, protecting core electronic components from radiation damage.
- Ultra-Low Signal Interference: High volume resistivity (≥1.0×10¹⁶ Ω·cm) and low dielectric loss, effectively avoiding interference with transponder signal transmission, ensuring clear and stable communication between deep space equipment and ground stations.
- Extreme Temperature Adaptability: Operates stably from -60℃ to 220℃, withstanding large temperature fluctuations in deep space, absorbing thermal stress to protect chips and welding gold wires from damage.
- Strong Adhesion & Customizability: Excellent bonding to PC, PMMA, PCB and aerospace metals (aluminum, copper, stainless steel); as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different deep space transponder 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 vacuum compatibility and adhesion.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly for 2-3 minutes to avoid air bubbles that affect sealing and signal stability.
- 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 transponder components without affecting vacuum performance.
- 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.
