Product Overview
Our Marine Electronic Potting Silicone Compound is a high-performance two-component room-temperature vulcanizing (RTV) potting material, specially engineered for harsh marine environments, a key part of HONG YE SILICONE’s full silicone product matrix. Also called encapsulation silicone, electronic silicone or marine potting glue, it is optimized for marine electronic pain points—strong salt-fog, high humidity, corrosion and temperature fluctuations. It cures into a dense protective layer, ensuring long-term stable operation of marine electronic components, far exceeding ordinary Electronic Potting Compound in marine environment adaptability.
Product Features & Advantages
1. Marine-specific corrosion & salt-fog resistance: Excellent resistance to marine salt fog, seawater corrosion and humid air, effectively isolating marine electronic components from seawater erosion and salt crystallization damage, extending service life in marine environments.
2. Superior waterproof & insulation performance: Low viscosity, good fluidity, forms a seamless waterproof barrier after curing; volume resistivity ≥1.0×10¹⁶ Ω·cm, dielectric strength ≥25 kV/mm, ensuring safe operation of marine electronics in humid conditions.
3. Fast room-temperature curing & marine-friendly: Rapid deep curing at room temperature (3-5 mins initial, 24 hrs full), no need for high-temperature equipment, adapting to marine equipment maintenance and on-site production needs.
4. UL94-V1 flame retardancy & EU ROHS compliance: Meets strict flame retardant standards to reduce marine fire risks, fully complies with EU environmental directives, supporting global marine electronic market access.
5. Strong adhesion & wide compatibility: Excellent bonding performance to PC, PP, ABS, PVC and marine-used metals, ensuring tight adhesion to marine circuit boards and modules without peeling in harsh marine conditions.
Technical Specifications
It is a two-component marine potting silicone with Component A and B both being viscous liquids; Component A has a viscosity of 500±100 cps. Mixed at 1:1 weight ratio, operable time is 30-120 minutes, initial curing time 3-5 minutes, full curing time 24 hours (affected by ambient temperature and humidity). After curing, it reaches Shore A hardness 25±2, thermal conductivity ≥0.2 W(m·K), dielectric constant 3.0～3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, UL94-V1 flame retardancy. Other models and customizable parameters (hardness, viscosity, curing speed) are available on request.
How to Use
1. Preparation: Fully stir Component A to mix settled black pigment evenly; shake Component B thoroughly to ensure uniform material composition without stratification, critical for marine waterproof performance.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent marine corrosion resistance and curing performance.
3. Deaeration (Optional): Place the mixed liquid into a vacuum container, deaerate for 3 minutes under 0.08MPa to remove air bubbles, ensuring a dense, bubble-free protective layer for marine electronics.
4. Potting & Curing: Pour the treated silicone onto marine electronic components, place at room temperature for curing. Proceed to the next process after initial curing, and ensure 24 hours for full curing to achieve optimal marine protection.
Application Scenarios
Specially designed for potting and protection of marine electronic components, including marine circuit boards, marine electrical modules, shipborne LED displays, marine sensors and marine communication equipment. It is suitable for marine electronic insulation, waterproofing, sealing and fixation, effectively resisting salt fog, seawater corrosion and humid marine environments. It reduces marine electronic failure rates and after-sales costs, becoming an essential material for marine electronic manufacturing, ship maintenance and marine equipment industries.
