Polyester Magnet Wire Enamels

Films composed of synthetic resin based on polyesters of terephthalic acid and polyhydric alcohols with or without a superimposed polyester film. The polyesters may be modified with other resins. The enamels can be used alone or two may be employed where one serves as an overcoat for the other. In addition, they may be overcoated with other polymers including nylon, amide-imide and polyester-imide enamels.
