Used primarily as a curing agent in epoxy resin systems, it provides excellent thermal and chemical resistance. Commonly applied in electrical insulating materials, such as in transformers, generators, and motors, due to its ability to form stable, durable cross-linked networks. Also utilized in coatings and composites requiring high performance under extreme conditions. Its low viscosity facilitates easy processing and impregnation in electrical windings. Suitable for both cast and laminated systems where long-term reliability is critical.
