    摘要: A process for producing a hermetic electric compressor for a refrigerating or air-conditioning apparatus using a refrigerant having a hydrofluorocarbon base which comprises a motor unit, a compressing unit driven by the motor unit and a sealed housing enclosing the motor unit and the compressing unit and stores a refrigeration oil on the bottom of the sealed housing, wherein a solventless varnish comprising a thermosetting resin having at least two (meth)acryloyl groups in one molecule, a low-viscosity vinyl or 1-alkylvinyl monomer having an ether or ester linkage as a reactive diluent and an organic peroxide as a reaction initiator is used as an insulating varnish to insulate and fix the magnet wires of the stator of the motor unit, and the solventless varnish is cured by heating at a temperature of from 153 to 180.degree. C. for from 0.5 to 3.5 hours.
