Produkt-Beschreibung
High-Tg Epoxy Resin for APG Process | Vacuum Casting & Electrical Insulating
LE-8216/LH-8216: UL-Certified Room Temperature Cure Epoxy for CT/PT Potting & Encapsulation
Flame-Retardant | UV/Weather-Resistant | High Dielectric Strength

Engineered for transformer encapsulation in Current Transformers (CT) and Potential Transformers (PT), LE-8216/LH-8216 delivers fast room temperature curing, eliminating energy-intensive ovens. This UL-certified, flame-retardant epoxy system combines a modified cyclic aliphatic epoxy resin (LE-8216) and weather-resistant anhydride hardener (LH-8216) for superior electrical insulation, moisture resistance, and vibration damping in demanding indoor/outdoor environments.

Key Features & Benefits
  • Fast Ambient Cure: Saves energy with rapid curing at room temperature.
  • Robust Protection: Shields CT/PT units from thermal shock, contaminants, and mechanical stress.
  • Superior Insulation: High dielectric strength (>18 kV/mm) for high-voltage applications.
  • Flame Retardant: UL 94 V-0 certified for safety-critical installations.
  • Weatherproof: Exceptional UV/environmental resilience for outdoor use.
  • Low-Viscosity Formulation: Penetrates intricate coils for void-free gap filling.
Applications

Ideal for:

  • Transformer potting & encapsulation (CT/PT units)
  • Medium/high-voltage insulators, bushings, and switchgear
  • Electrical components requiring moisture-resistant protection
  • Flame-retardant insulation in power infrastructure
Processing Methods
