摘要: A corona-resistant wire enamel composition is described comprising a polyimide, polyamide, polyester, polyamideimide, polyesterimide, or polyetherimide resin and from about 1% to 35% by weight of dispersed alumina particles finite size less than 0.1 micron, the being therein high shear mixing. method providing corona resistant one two-stage insulations for an electrical conductor employing above compositions insulated with coating are also disclosed.
