This document provides information on an epoxy molding resin. It can be used for molding outdoor heavy electric machinery, as a substitute for SF6 gas in high-voltage switchgear, and for molding high-voltage transformers, bushings, housings, and brackets. The resin has excellent electrical insulation and mechanical strength. It also meets customers' molding requirements. The document provides storage, curing, and usage instructions, and lists the resin's properties including tensile strength, flexural rigidity, hardness, and electrical breakdown voltage.
