VERMEHERDANDE REAKTIONSBLANDNING FOR IMPREGNERING AV ISOLERINGAR AV ELEKTRISKA VERKTYG OCH FOR FRAMSTELLNING AV PLASTER MED ELLER UTAN INLEGG

摘要

Addition complexes of tertiary amines and boron trichloride of the general formula BCl3.NR 1R2R 3 are used as an accelerator system for a heat-curing reaction resin mixture of purified polyisocyanate and polyepoxy resin compounds. Insulation impregnated with this reaction resin mixture exhibits high thermal stability in the hardened condition and can be used at high operating temperatures.
