Casting Type Epoxy Resin
|
|
Epoxy resin with acid anhydride curing agent's combination, with excellent electrical properties, the use of type is suitable for filling products, while the NPEC series dedicated perfusion of the modified resin, its hardened calorific value is small, the small volume change at the same time, for the high reliability and transformer, current transformer, resin insulator, switch device, such as electric infusion products, is quite applicable.
