Product Overview
Our Electronic Potting Silicone, also known as potting silicone or Silicone Encapsulant, is a specialized protective solution engineered specifically for traffic signal controllers. As an experienced RTV 2 Silicone Rubber manufacturer, we focus on industrial-grade silicone materials for traffic infrastructure. This liquid silicone outperforms ordinary Potting Compound, with outstanding weather resistance and signal interference resistance, perfectly adapting to the outdoor, harsh working environment of traffic signal controllers. Technical Specifications
This two-component Electronic Potting Silicone is an Addition curing silicone, with fully customizable core parameters. Both Part A and Part B are liquid; Part A requires thorough stirring to redistribute settled fillers before use. It follows a customizable weight mixing ratio, with vacuum defoaming recommended at 0.01MPa for 3 minutes for bubble-free encapsulation. It can be cured at room temperature or by heating, with full curing time of 24 hours (affected by ambient temperature and humidity). Key customizable parameters include hardness, viscosity, operation time, thermal conductivity and insulation performance, all tailored to traffic signal controller requirements.
Product Features & Advantages
- Superior insulation performance: High dielectric strength and volume resistivity, preventing short circuits caused by outdoor moisture or dust, ensuring safe and stable operation of traffic signal controllers. - Excellent waterproof & dustproof: Withstands rain, snow, dust and dew in outdoor traffic environments, preventing water intrusion and component damage. - Wide temperature adaptability: Operates stably from -60℃ to 220℃, adapting to extreme temperature fluctuations (winter cold, summer heat), protecting controller chips and welding wires. - Strong multi-material adhesion: Bonds tightly to PC, PMMA, PCB, aluminum, copper and stainless steel, ensuring firm encapsulation of traffic signal controller components. - Weather & corrosion resistance: Withstands outdoor UV radiation, ozone and chemical erosion, extending the service life of traffic signal controllers. - Signal-friendly formula: Does not interfere with traffic signal transmission, ensuring accurate and timely signal output for traffic management. - Dual curing flexibility: Room-temperature or heated curing adapts to different traffic signal controller production processes, improving manufacturing efficiency.
How to Use
1. Before mixing, fully stir Part A to evenly distribute settled fillers, and shake Part B thoroughly to ensure uniform consistency. 2. Mix Part A and Part B according to the specified weight ratio, stirring thoroughly for uniform mixing. 3. Degas if needed: Put the mixed glue into a vacuum container, degas at 0.01MPa for 3 minutes, then pour into traffic signal controller components. 4. Cure at room temperature or by heating; basic curing completes before the next process, and full curing takes 24 hours (environment temperature and humidity have a significant impact on curing effect).
