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.
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.
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
