Product Overview
Our Electronic Potting, also called potting glue or encapsulation silicone, is a high-performance Silicone Encapsulant specially engineered for railway crossing gate controls—the critical component ensuring railway crossing safety. As a professional supplier of Thermally Conductive Potting Compound and industrial silicone solutions, we optimize this product for railway scenarios: it bonds perfectly to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), with excellent waterproof, moisture-proof, corrosion-resistant, insulation and shock absorption performance. It effectively protects crossing gate control electronics from vibration, extreme temperatures, dust, humidity and chemical erosion, ensuring accurate signal transmission and reliable operation of railway crossing gates. Technical Specifications
Our Electronic Potting has stable performance with fully customizable parameters; key specifications are as follows: it is a dual-component addition-curing liquid silicone (A and B), with A component needing full stirring to mix settled fillers evenly and B component needing thorough shaking. The weight ratio of A and B components is adjustable, with optional vacuum defoaming (0.01MPa for 3 minutes) before pouring. It supports room-temperature or heated curing, with basic curing for next-process operation and full curing within 24 hours (environment temperature and humidity affect curing speed). It operates continuously from -60℃ to 220℃, with high dielectric strength, volume resistivity, low volatility, high strength and excellent adhesion. Shelf life is 12 months when sealed, non-hazardous for general chemical transportation. Product Features & Advantages
- High-Level Insulation Performance: Excellent electrical insulation, with high dielectric strength and volume resistivity, preventing short circuits caused by external factors, ensuring safe operation of railway crossing gate control systems.
- Strong Anti-Vibration & Impact Resistance: Absorbs vibration from passing trains and impact from external forces, protects control board chips and welding wires from damage, ensuring stable signal transmission and gate operation.
- Outdoor Weather Resistance: Stable performance from -60℃ to 220℃, resisting severe cold, high temperature, rain, snow and humidity, adapting to long-term outdoor railway crossing environments.
- Corrosion & Ozone Resistance: Resists outdoor ozone, railway chemicals and harsh weather, extending the service life of crossing gate control components and reducing maintenance costs.
- Strong Adhesion & Low Volatility: Bonds firmly to various railway equipment materials, with high structural strength; low volatile content, no contamination to precision electronic components.
- Dual Curing & Customizable: Available in addition-curing and condensation-curing types, with adjustable curing speed and viscosity, adapting to railway equipment production workflows.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A to mix settled fillers evenly, and shake Component B thoroughly to ensure uniform viscosity; slight stratification during storage does not affect performance after stirring.
- Component Mixing: Strictly mix Component A and Component B according to the specified weight ratio, stirring continuously until homogeneous to ensure optimal curing effect.
- Vacuum Defoaming: After mixing evenly, place the mixed glue in a vacuum container and defoam at 0.01MPa for 3 minutes to remove air bubbles, ensuring dense, bubble-free encapsulation.
- Curing Process: Pour the defoamed glue into railway crossing gate control components, cure at room temperature or heat. Proceed to the next process after basic curing, and ensure full curing (24 hours) for optimal protection and performance.
