HONG YE SILICONE’s Electronic Potting Silicone for Railway Electronics (Models HY-9055/HY-9045) is a high-performance two-component Silicone Encapsulant tailored for railway electronic components. It is liquid before curing, forming a flexible rubber after curing with excellent shock resistance. Available in addition and condensation curing types, it features non-exothermic curing, low shrinkage, and extreme temperature resistance (-60℃), complying with ISO9001, CE and railway industry standards. With customizable parameters, it pairs with our Silicone raw materials and silicone encapsulant to ensure stable operation of railway electronics, meeting global B2B procurement requirements for railway equipment.
Product Overview
As a core railway-grade product of HONG YE SILICONE, our Electronic Potting Silicone (also called Silicone Potting Compound or Electronic Encapsulation Adhesive) is engineered to protect sensitive railway electronic components. Different from epoxy potting resin, this two-component silicone cures without exotherm or corrosion, with small shrinkage and excellent flexibility. It is widely used for potting railway circuit boards, ballasts, transformers, LEDs, LCDs and CPUs, forming a reliable thermal conductive and insulating system, adapting to harsh railway operating environments. Product Features
1. Gentle & safe curing: Non-exothermic and non-corrosive during curing, small shrinkage, avoiding damage to precision railway electronic components, suitable for fragile railway circuit boards and chips.
2. All-round protection: Excellent waterproof, moisture-proof, chemical resistance, yellowing resistance and anti-static performance, effectively isolating railway electronics from harsh outdoor environments.
3. Easy maintenance: The cured rubber layer can be easily peeled off for component repair and replacement, reducing railway equipment maintenance costs and downtime.
4. Extreme temperature & shock resistance: Stable elasticity in a wide temperature range, no crystallization at -60℃, strong shock resistance to adapt to railway vibration during operation.
5. Long service life: Excellent weather resistance and anti-aging performance, stable light decay, sealing and brightness, extending the service life of railway electronic components.
Technical Specifications
Models HY-9055/HY-9045: Two-component Addition Curing Silicone, 1:1 weight mixing ratio. Liquid before curing, forming flexible rubber after curing. It can be cured at room or elevated temperature, with full curing in 24 hours (environment temperature and humidity affect curing speed). Defoaming is available at 0.08MPa for 3 minutes. Cured hardness, viscosity and operating time are fully customizable to match different railway electronic components. Application Scenarios
Widely applied in potting and protection of various railway electronic components, including railway circuit boards, electronic ballasts, electronic transformers, train LED lighting, LCD displays, CPU modules and signal transmission components. It is suitable for train carriages, railway stations, trackside equipment and signal systems, effectively resisting vibration, temperature changes, moisture and dust, ensuring stable operation of railway electronic systems.
Core Value for Buyers
1. Enhance operational safety: Reliable protection reduces railway electronic failure rate, avoiding signal interruptions or equipment malfunctions, ensuring railway operation safety.
2. Reduce maintenance costs: Easy-to-peel rubber layer facilitates component repair, extending service life and reducing after-sales and replacement costs.
3. Adapt to harsh environments: Extreme temperature and shock resistance fully match railway outdoor and vibration operating conditions, improving product applicability.
4. Compliance assurance: Meets international certifications and railway industry standards, avoiding trade barriers, suitable for global railway equipment markets.
How to Use
1. Pre-mixing: Fully stir Component A to mix settled fillers evenly, and shake Component B thoroughly before use to ensure uniform performance.
2. Mixing: Stir Component A and B in 1:1 weight ratio until fully fused, avoiding uneven mixing that affects curing effect.
3. Defoaming: Put mixed glue into a vacuum container, defoam at 0.08MPa for 3 minutes, then proceed to potting to avoid bubbles affecting sealing performance.
4. Potting & curing: Pour defoamed glue into railway electronic components, cure at room or elevated temperature; enter next process after basic curing, full curing in 24 hours.
