Achieve deep penetration and flawless insulation with our Low Viscosity Flame Retardant Epoxy Resin, meticulously formulated for void-free transformer coil impregnation. This UL 94 V-0 rated epoxy is engineered to flow effortlessly into the tightest interstices of complex winding structures within power transformers, toroidal coils, and chokes, eliminating air pockets and ensuring complete encapsulation. Its low initial viscosity is key to achieving maximum electrical insulation integrity, preventing partial discharge and enhancing dielectric strength by removing voids that compromise performance. Despite its excellent flow characteristics, the resin cures to form a rigid, flame-retardant barrier that significantly enhances fire safety in electrical equipment. It delivers robust protection against moisture, chemicals, and environmental degradation, while its inherent flame retardant properties meet critical safety standards. The cured system exhibits good thermal shock resistance and a favorable CTE match to common winding materials, reducing stress during temperature fluctuations. This epoxy is ideal for vacuum pressure impregnation (VPI) or dip processes, ensuring reliable, high-yield production of transformers requiring superior electrical insulation, fire resistance, and long-term operational reliability. Optimize your coil impregnation process with this high-performance, low-viscosity, flame-retardant solution.
