Abstract
Abstract Electrical conductors can be coated with a cured, thermosetting powder coating which, in its uncured state comprises a saturated, carboxyl group-containing polyester resin, an epoxy resin, an acrylic resin and, optionally, a cure catalyst, benzoin and/or a polyamide resin to provide insulative coatings with reduced air entrapment and improved dielectric strength.
