LE-9217F is a modified BPA (bisphenol A) type epoxy resin.

LH-9217F is a liquid modified carboxylic anhydride hardener.

Two-component saturated cyclic epoxy resin system without pre-mixed fillers, liquid at room temperature.

Excellent resistance to thermal shock, superior environmental resistance, and superior mechanical and dielectric properties.

Fast-Cure Flame Retardant Epoxy Resin System for High-Volume Transformer Production
Accelerate your transformer manufacturing with our Fast-Cure Flame Retardant Epoxy Resin System. Engineered for high-volume production environments, this UL 94 V-0 rated epoxy significantly reduces cycle times for potting, encapsulating, and impregnating transformer coils and assemblies without compromising fire safety or electrical performance. Its optimized chemistry delivers a rapid gel and cure profile at moderate temperatures, enabling faster mold turnover and increased throughput for transformer production lines. Despite the fast cure, the resin achieves deep penetration for void-free insulation and forms a rigid, flame-retardant barrier around windings and components, providing essential protection against electrical faults and fire hazards. It offers excellent electrical insulation properties, including high dielectric strength and tracking resistance (CTI), ensuring long-term transformer reliability. The cured system exhibits good thermal stability, moisture resistance, and mechanical toughness to withstand operational stresses. This epoxy resin system is ideal for automated dispensing and processes requiring quick handling strength. Reduce your production bottlenecks while maintaining the highest standards of flame retardancy (UL 94 V-0) and electrical insulation integrity with this high-performance, fast-curing solution tailored for efficient transformer manufacturing.
