Industry Impact


Epoxy-based electrical insulation solutions are pivotal to the reliability and sustainability of modern power infrastructure. By minimizing energy losses and extending equipment lifespan, they reduce maintenance costs and environmental footprint. For example, epoxy-insulated dry-type transformers eliminate the risk of oil spills, making them ideal for urban and environmentally sensitive areas. Moreover, advancements in epoxy formulations—such as halogen-free and flame-retardant variants—align with global safety standards, enabling safer operation in high-risk environments. As the demand for smarter, greener grids grows, epoxy resin remains at the forefront of innovation in electrical insulation technology.


Fast-Cure Epoxy Curing Agent for Productivity in MV Switchgear Manufacturing & Repairs
Accelerate production throughput with our Fast-Cure Epoxy Curing Agent optimized for MV switchgear manufacturing and
field repairs. This innovative hardener reduces gel time by 40% versus standard systems while maintaining low exotherm – critical for potting large CTs, breaker poles, and bushing inserts without thermal stress. Achieve demold readiness in 90 minutes at 80°C, significantly shortening cycle times for vacuum pressure impregnation (VPI) processes. The balanced reactivity ensures thorough flow into complex windings before gelation, preventing dry spots in instrument transformers. Despite rapid curing, the encapsulation delivers superior electrical properties: partial discharge <3pC at 1.5Ur and dielectric strength >20kV/mm. The formulation is compatible with quartz and alumina fillers for thermal expansion control in 36kV systems. Its extended pot life (45 minutes at 25°C) facilitates batch processing of multiple units. This switchgear potting agent minimizes energy consumption in curing ovens while meeting IEC 60296 compatibility requirements. Implement this solution to boost manufacturing capacity and reduce downtime during critical switchgear maintenance operations.
