ABSTRACT:
A formulation which may be applied to a substrate to produce a flexible, high temperature, thermally stable and color stable film thereon. The formulation comprises a poly(1,3-imidazolidine-2,4,5-trione) polymer, a free radical scavenger in an amount sufficient to inhibit cleavage and cross-linking of the polymer by action of oxygen thereon, and a solvent for the polymer. Also disclosed are a method for applying a flexible, high temperature, thermally stable and color stable color coating to a polyimide substrate; the substrate so coated; and an insulated conductor assembly having a polyimide insulative cover and an imidazolidine trione based-top-coating over the cover.
