Title: Method of making an electrical article

Abstract: A binding tape is made by coating a ribbon having glass fibers in the fill direction and a flexible, thermally stable fiber in the warp direction, with a swellable resin composition and removing the excess composition. The tape is lap-wound over an electrical conductor which is then immersed in solventless resin under pressure. The conductor is removed from the solventless resin and the tape prevents the solventless resin from seeping out before it is cured.
