epoxy adhesives, etc. With the many advantages, e.g. long-term
storage at room temperature, low freezing point, small
volatilization and low toxicity, MTHPA is widely used in electric
machines, dry-type transformers, high voltage switches, mutual
inductance equipments, horizontal output transformers, household
appliances capacitors, power capacitors and resistances, and the
impregnating, casting and wrapping of integrated circuits.
