Product Overview
Our Electronic Potting Silicone is specialized for hydrogen storage monitoring systems, designed for encapsulation, sealing, filling and pressure protection of their electronic components. As a leading manufacturer of liquid silicone and addition curing silicone, we craft this product to withstand hydrogen-induced corrosion and harsh environmental stressors. The low-viscosity liquid cures into a flexible solid, excelling in bonding with PC, PMMA, PCB, CPU, aluminum, copper and stainless steel. It extends monitor service life, ensures data accuracy, and is far superior to epoxy potting resin in flexibility and hydrogen environment adaptability.
Key Features & Advantages
1. Hydrogen Environment Adaptability: Outstanding anti-corrosion, waterproof and moisture-proof performance, effectively preventing hydrogen-induced corrosion and moisture intrusion.
2. Wide Temperature Tolerance: Operates stably from -60℃ to 220℃, absorbing thermal cycling stress to protect chips and welding gold wires. 3. Superior Insulation: High dielectric strength and volume resistivity, avoiding electrical interference and ensuring accurate signal transmission. 4. Dual Curing Options: Available as addition and Condensation Curing Silicone Mold Rubber, with room-temperature or heated curing to boost production efficiency. 5. High Reliability: Ultra-low volatile content reduces contamination, while high strength and excellent adhesion ensure long-term structural integrity.
6. Chemical Resistance: Resists ozone, chemical erosion and hydrogen-related contaminants.
How to Use
1. Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously for uniformity.
2. Precision Mixing: Adhere to a 1:1 weight ratio of Component A to B, stirring slowly for 2-3 minutes to avoid air bubbles.
3. Degassing (Optional): Place mixed adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate bubbles, ensuring full penetration into tiny gaps.
4. Curing: Pour degassed mixture into component housings; cure at room temperature for 24 hours (full solidification) or accelerate via heating. Maintain 40-60% humidity for optimal results, as temperature and humidity affect curing speed.
