The LE-184/LH-8504 epoxy system is a weather-resistant, multi-component formulation engineered for outdoor high-voltage electrical insulation. Featuring modified BPA epoxy (LE-184), anhydride hardener (LH-8504), flexibilizer (LF-660), and accelerator (LZ-622), it delivers exceptional UV/erosion resistance, thermal shock stability, and superior dielectric performance. Ideal for APG or vacuum casting processes in harsh environments.
| Feature | Advantage |
|---|---|
| UV & Weather Resistance | Withstands outdoor exposure, prevents erosion & yellowing |
| Flexibilizer LF-660 (0-20 pbw) | Enhances crack resistance under thermal cycling |
| Accelerator LZ-622 (0-0.4 pbw) | Speeds curing for high-volume production |
| APG & Vacuum Casting Compatible | Adapts to existing manufacturing setups |
| High Dielectric Strength | 25-35 kV/mm (IEC 60243-1) for outdoor insulators |
| Low Water Absorption | 0.10-0.20% (23°C/10d) ensures long-term integrity |
| Solvent-Free | Eco-friendly, low-VOC processing |
