Our Electronic Potting Silicone is a high-performance two-component potting material tailored for space-based solar arrays, designed to protect PCB boards, solar array control modules, connectors and core electronic components. As a leading Mold Making Silicone and liquid silicone manufacturer, we craft this product to meet the strict anti-radiation, extreme temperature resistance and vacuum adaptability requirements of space environments. It provides comprehensive encapsulation, sealing, filling and pressure protection for sensitive electronic components, forming a reliable thermal conductive and insulating system to ensure stable energy conversion and transmission of space-based solar arrays. Key Features & Advantages
1. Space environment adaptability: Ultra-low volatile content, no outgassing in vacuum, avoiding contamination of solar array components.
2. Comprehensive protection: Excellent corrosion resistance, waterproof, moisture-proof, dust-proof, shockproof and flame retardancy, with good ozone and chemical erosion resistance, adapting to harsh space conditions.
3. Extreme temperature resistance: Operates stably from -60℃ to 220℃, absorbing internal stress from extreme temperature cycles to protect chips and welding gold wires, no crystallization at low temperatures.
4. Strong adhesion: Bonds excellently with PC, PMMA, PCB and space-grade metals (aluminum, copper, stainless steel), ensuring firm encapsulation.
How to Use
1. Before mixing, fully stir Component A to evenly distribute settled fillers, and shake Component B thoroughly to ensure uniformity.
2. Mix Component A and B according to the specified weight ratio for space-grade precision requirements.
3. Degas as needed: Stir the mixed adhesive evenly, place in a vacuum container, degas at 0.01MPa for 3 minutes, then pour for use.
4. This Addition Curing Silicone product can be cured at room temperature or Heating and curing, proceed to the next process after initial curing, with full curing in 24 hours. Ambient temperature and humidity significantly affect curing speed, so strict control is recommended for space component manufacturing. Application Scenarios
This Silicone Potting Compound is mainly used for encapsulation, sealing, filling and pressure protection of electronic components in space-based solar arrays, including solar array PCB boards, control modules, connectors, energy storage units and signal transmission components. It ensures stable operation of solar arrays in extreme space environments (vacuum, radiation, extreme temperature changes), reduces failure risks, improves energy conversion efficiency and extends service life. It can be used with Rapid prototyping silicone to produce solar array component prototypes, accelerating R&D efficiency for aerospace manufacturers and reducing production costs.
