Polyepoxide potting resin compositions and electrically conductive coils impregnated therewith.

摘要

Compositions comprising a bisphenol diglycidyl ether, an inner anhydride of a dicarboxylic acid, a diglycidyl ether of a C3-6 aliphatic diol and a specifically defined boron trichloride-trialkylamine adduct are useful as potting resins for electrically conductive coils, especially superconducting magnet coils. They have low viscosity at relatively low temperatures and cure rapidly at temperatures in the range of about 80-100 DEG C.
