Product Overview
Our Electronic Potting Silicone, also called Potting Compound , Electronic Encapsulation Adhesive and silicone encapsulant, is a professional two-component potting material designed for spacecraft avionics. After mixing with curing agent, it cures into a solid form, providing comprehensive protection for sensitive electronic components. As a leading Mold Making Silicone and liquid silicone manufacturer, we tailor this product to meet the strict standards of aerospace industry, effectively isolating spacecraft avionics from cosmic radiation, extreme temperature changes and vacuum environments. Key Features & Advantages
1. Extreme environment adaptability: Works stably from -60℃ to 220℃, absorbing internal stress from high-temperature cycles to protect chips and welding gold wires in spacecraft. 2. Comprehensive protection: Offers excellent corrosion resistance, waterproof, moisture-proof, dust-proof, shockproof and confidentiality, suitable for vacuum and cosmic radiation environments. 3. High reliability: Low volatile content, high strength and good ozone/chemical erosion resistance, complying with aerospace quality standards. 4. Strong adhesion: Bonds well with PC, PMMA, PCB, CPU and aerospace metals (aluminum, copper, stainless steel). 5. Premium quality: Produced with high-purity Silicone raw materials, consistent with our Platinum cured mold silicone quality control system, ensuring stable performance. 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 aerospace-grade precision. 3. Degas as required: 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 heated; 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.
