ISOLASJONSB ND FOR FREMSTILLING AV EN ISOLASJONSHYLSEGNERT MED EN VARMEHERDNENDE EPOKSYHARPIKS-SYREANHYDRID-BLANDING, FOR ELEKTRISKE LEDERE.

摘要

An insulating tape for manufacturing an insulating sleeve for electric conductors, impregnated with a heat-hardening epoxy resin-acid anhydride hardener mixture, contains a self-hardening bonding agent-accelerator composition of an epoxy resin as the bonding agent and a quarternary onium salt as the accelerator. To prevent migration of the charge carriers present in the accelerator, the accelerator further has a group which can react with the bonding agent-impregnating resin mixture. This group causes a fixation of the accelerator in the lattice produced during the hardening.
