Elevate transformer reliability with our High Tg Flame Retardant Epoxy Encapsulant, designed for superior insulation and robust protection. This specialized resin combines exceptional thermal performance (high glass transition temperature) with proven flame retardancy (UL 94 V-0 compliant) to meet the rigorous demands of power transformers, instrument transformers, and reactor coils. Its high Tg ensures outstanding dimensional stability and retains excellent mechanical and electrical properties even at sustained high operating temperatures, preventing softening or creep under load. The formulation delivers critical flame retardant properties without compromising on essential electrical insulation performance, featuring high dielectric strength and robust tracking resistance (high CTI). Engineered for effective coil impregnation and potting, its optimized rheology ensures thorough wetting and void-free encapsulation of intricate winding assemblies, protecting against partial discharge and electrical failure. This epoxy resin also provides formidable resistance to thermal cycling, moisture ingress, and harsh environmental factors, safeguarding transformer integrity for decades. Suitable for automated dispensing or manual potting processes, it offers a reliable cure profile. This high-performance, flame-retardant encapsulant is the cornerstone for building transformers that prioritize safety (fire resistance), longevity, and unwavering electrical insulation integrity under thermal stress.
