Product Features & Advantages
- Low Viscosity & Self-Defoaming: Excellent fluidity and self-defoaming ability, easily potting tiny, complex electronic components of railway signal devices, ensuring no air bubbles and stable protection.
- Detachable & Repairable: Encapsulated components can be taken out for repair/replacement, then patched without traces, reducing railway signal system maintenance costs and downtime.
- Flame-Retardant & Safe: UL94-HB flame-retardant rating, meeting international railway safety standards, eliminating fire risks in signal equipment.
- No Shrinkage & Stable Curing: No shrinkage during curing, avoiding damage to precision signal components, ensuring long-term stable operation in harsh environments.
- Harsh Environment Adaptability: Integrates waterproof, dust-proof, corrosion-resistant, shock-resistant and anti-electromagnetic interference functions, adapting to outdoor railway environments (extreme temperature, rain, dust).
- Flexible Curing & Mass Production: Long room-temperature storage time, fast heating curing, suitable for both manual and automated production of railway signal equipment.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Check the potting silicone for layering; stir evenly if layered (does not affect performance), ensuring uniform viscosity.
- Potting Operation: Pour the low-viscosity silicone into railway signal component housings, relying on self-defoaming performance to eliminate air bubbles (vacuum defoaming can be used for high-precision components).
- Curing Process: Cure at room temperature (long storage time) or heat to accelerate curing, ensuring full curing to achieve reliable protection.
- Repair (if needed): Take out the damaged component for repair/replacement, then patch with the same potting silicone to restore protection without traces.
