Product Description

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.

Key Features & Advantages
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
Applications

Built for outdoor electrical components:

  • HV bushings, insulators & surge arresters
  • Transformer encapsulation
  • Outdoor switchgear (12-40.5 kV)
  • Solar/Wind energy infrastructure
  • Railway electrification components

Frequently Asked Questions (FAQ)
Q1: What's the role of LF-660 and LZ-622?
A: LF-660 (0-20 pbw) improves flexibility & crack resistance. LZ-622 (0-0.4 pbw) accelerates curing - critical for APG production.
Q2: How should I store components?
A: Store in sealed containers at 18-25°C. Shelf life: 24 months. Avoid moisture - hardener is humidity-sensitive.
Q3: What processing methods are supported?
A: Optimized for:
APG: Mold temp 130-150°C | Gel time 10-50 min
Vacuum Casting: Cure 80-100°C | Gel time 3-6h
Post-cure: 130-140°C*6-10h for all methods
Q4: How is filler pre-treated for HV applications?
A: Silica filler must be pre-dried (moisture ≤0.2%). Use thin-film degassing mixers for consistent dispersion.
Q5: Is this system suitable for coastal environments?
A: Yes! UV resistance + low water absorption (0.10-0.20%) prevents salt corrosion & tracking.
