Product Overview
Our Electronic Potting Silicone is specialized for spaceborne laser communication systems, designed for encapsulation, sealing, waterproofing and fixing of their core electronic components. As a leading manufacturer of liquid silicone and Addition Curing Silicone, we optimize the formula to resist space radiation, vacuum environment and extreme temperature changes, while ensuring ultra-low signal loss to protect laser communication modules. It outperforms epoxy potting resin in low-temperature flexibility and signal compatibility, cures at room temperature with 24-hour full solidification, and ensures reliable protection for spaceborne electronic components, extending equipment service life and reducing space maintenance costs. Key Features & Advantages
- Space Environment Adaptability: Resists space radiation, vacuum outgassing (ultra-low volatile content) and extreme temperatures, ensuring stable performance in harsh spaceborne conditions.
- Low Signal Loss & High Insulation: Ultra-low dielectric loss, dielectric constant of 3.0~3.3 (1.2MHz), ensuring no laser signal attenuation; high dielectric strength (≥25 KV/mm) and volume resistivity (≥1.0×10¹⁶ Ω.cm) for safe insulation.
- Excellent Adhesion & Versatility: Superior bonding performance to PC, PP, ABS, PVC and various metals, suitable for diverse spaceborne laser communication component substrates.
- Friendly Curing Process: 1:1 weight mixing ratio, easy to operate; rapid room-temperature deep curing, 3-5 hours basic curing and 12-24 hours full curing, adaptable to space component production.
- High Reliability & Customizability: UL94-V1 flame retardancy, non-toxic and non-hazardous; hardness, viscosity and operation time can be customized to match different spaceborne laser communication components.
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 which affects performance.
- Precision Mixing: Strictly follow the 1:1 weight ratio of Component A to B, stirring slowly and evenly to ensure consistent performance and avoid introducing air bubbles.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.08MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of laser communication components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature, enter the next process after basic curing (3-5 hours), and achieve full solidification in 12-24 hours. Note: Environment temperature and humidity have a significant impact on curing speed.
