HONG YE SILICONE Electronic Potting Silicone for Subsea Power Distribution is a high-performance two-component Addition Curing Silicone, also named Electronic Potting Compound and Silicone Encapsulant. It integrates waterproof, moisture-proof, thermal conductivity, flame retardancy and insulation, curing into a dense protective layer after mixing with curing agent to shield core components of subsea power distribution systems. Featuring ultra-low volatile content, superior adhesion to marine-grade metals and substrates, and dual curing options, it ensures long-term reliability under extreme deep-sea conditions (high pressure, seawater corrosion, low temperature), fully meeting international marine industry standards and crafted from high-purity Silicone raw materials.
Product Overview
Our Electronic Potting Silicone is exclusively customized for subsea power distribution systems, designed for encapsulation, sealing, filling and pressure protection of precision components like subsea circuit boards, power distribution modules and connection terminals. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula to resist seawater erosion, deep-sea high pressure, low-temperature thermal shock (from -60℃ to 220℃) and marine chemical corrosion. The low-viscosity liquid penetrates tiny gaps of components, cures into a flexible and robust solid, and outperforms epoxy potting resin in water resistance and deep-sea environment adaptability, effectively protecting subsea power distribution signal stability and equipment service life.
Key Features & Advantages
- Deep-Sea Environment Resistance: Outstanding waterproof, moisture-proof and anti-corrosion performance, resisting seawater erosion, marine biofouling and deep-sea high pressure (adapting to 0-1000m subsea depth).
- Wide Temperature Tolerance: Operates stably from -60℃ to 220℃, absorbing thermal cycling stress in subsea temperature changes to protect chips and welding gold wires from damage.
- Superior Insulation & Thermal Management: High dielectric strength and volume resistivity avoid electrical interference in wet subsea environments, while excellent thermal conductivity dissipates heat generated by power distribution work.
- Dual Curing Flexibility: Available as addition and Condensation Curing Silicone Mold Rubber, supporting room-temperature or heated curing to adapt to different subsea component production lines.
- High Adhesion & Reliability: Excellent bonding strength to PC, PMMA, PCB, CPU and marine-grade aluminum, copper, stainless steel, preventing delamination in high-pressure subsea conditions; ultra-low volatile content avoids component contamination.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously for 2-3 minutes to ensure uniformity (critical for subsea waterproof performance).
- Precision Mixing: Strictly follow a 1:1 weight ratio of Component A to B, stirring slowly and evenly for 3 minutes to avoid introducing air bubbles.
- Degassing (Optional): Place the mixed adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate bubbles, ensuring full penetration into tiny gaps of precision components.
- Curing: Pour the degassed mixture into subsea component housings; cure at room temperature for 24 hours (full solidification) or accelerate via heating (80-100℃ for 15 minutes). Note: Temperature and humidity significantly affect curing speed, maintain 40-60% humidity for optimal results.
