Description de produit
Outdoor Epoxy Resin & Hardener | UV-Resistant High-Voltage Insulation for APG & Casting
Product Overview

The LE-9518/LH-9518 Outdoor Epoxy Resin System is a premium two-component, non-premixed solution engineered for demanding outdoor electrical insulation applications. Designed for both Automatic Pressure Gelation (APG) and Vacuum Casting processes, this hot-curing epoxy resin delivers exceptional resistance to UV radiation, thermal shock, and environmental stress cracking.

Key Features & Advantages
  • Extreme Weather Resistance: Superior UV stability and thermal shock resilience (-40°C to 150°C)
  • High Dielectric Performance: Critical for 35kV+ outdoor insulation systems
  • Dual-Process Compatibility: Optimized for APG (fast curing) and vacuum casting (precision molding)
  • Low Volatility: Vapor pressure <0.01 Pa (resin) and 0.5 Pa (hardener) enhance workplace safety
  • Mechanical Robustness: Withstands high mechanical stress in power infrastructure
