Technical Specifications
This two-component Electronic Potting Silicone (Model HY-9325) has Part A and Part B both as viscous liquid, each with a viscosity of 500±100 cps. It adopts a 1:1 weight mixing ratio, with an operable time of 30～120 minutes, basic curing time of 3～5 minutes, and full curing time of 24 hours. Cured, it has a Shore A hardness of 25±2, thermal conductivity of ≥0.2 W(m·K), dielectric strength of ≥25 kV/mm, dielectric constant of 3.0～3.3 (1.2MHz), volume resistivity of ≥1.0×1016 Ω·cm, and UL94-V1 flame retardancy. All parameters can be customized to meet LED street light requirements.
Product Features & Advantages
- Excellent waterproof & insulation: High dielectric strength and volume resistivity, effectively preventing water and dust intrusion, avoiding short circuits and ensuring safe operation of LED street lights in outdoor rainy environments. - Fast room-temperature curing: Enables deep curing at room temperature, shortens production cycles, improving manufacturing efficiency for LED street light mass production. - Strong adhesion: Excellent bonding to PC, PP, ABS, PVC and various metals, ensuring firm sealing of LED street light components, preventing detachment under outdoor weathering. - Flame retardant: UL94-V1 flame retardancy, avoiding fire hazards, meeting strict outdoor lighting safety standards. - Weather & UV resistance: Withstands outdoor UV radiation, rain and temperature changes, no yellowing or performance degradation, extending LED street light service life. - RoHS compliance: Fully meets EU RoHS directives, conforming to international environmental standards, suitable for global LED lighting markets. - Easy operation: 1:1 weight mixing ratio, low viscosity and easy pouring, suitable for complex LED street light component structures.
How to Use
1. Before mixing, fully stir Part A to evenly distribute settled black pigment, and shake Part B thoroughly to ensure uniformity. 2. Mix Part A and Part B at a 1:1 weight ratio, stirring thoroughly for uniform mixing. 3. Degas if needed: Put the mixed liquid into a vacuum container, degas at 0.08MPa for 3 minutes to remove air bubbles, then pour into LED street light components. 4. Cure at room temperature; basic curing completes before the next process, and full curing takes 24 hours (environment temperature and humidity affect curing effect).
