摘要： A flexible mica tape having a low gel time is prepared from a composition of an epoxy resin, an organotin salt, and catechol or pyrogallol. A mica sheet is immersed in the composition and the solvent is evaporated to form a tack-free A-staged resin. A conductor is wound with the tape and is impregnated with an impregnating resin using vacuum-pressure impregnation.
