High-Tg UV/Weather-Resistant Electrical Insulating Epoxy Resin with High Dielectric Strength for Transformer Encapsulation

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

*Add LC-series paste for UV-stable pigmentation.

This electrical-grade epoxy system excels as a potting compound for transformer manufacturing, offering unmatched electrical component protection. Its saturated cyclic aliphatic structure ensures long-term stability under thermal cycling, while silica-filled reinforcement enhances mechanical strength and dielectric performance. Compatible with vacuum casting and APG processes, it integrates seamlessly into existing production lines--ideal for creating reliable, flame-retardant CT/PT encapsulation with minimal energy input.
