Epoxy encapsulation compounds with improved thermal shock and reversion resistance

Liquid epoxy resins, cured with acid anhydrides, comprise, in terms of total usage volumes, the most important class of castable insulation compounds. They are used for encapsulation and impregnation of transformers, lifting magnets, motor stators, solenoids and other coils, for casting stand off bushings and for potting multipliers and other electrical components.
