Polyamideimide coating compositions for magnet wire which exhibit solvent or varnish-induced craze resistance. The polyamideimide compositions include a compound selected from the group consisting of diacid compounds, trimellitic anhydrides, benzophenonetetracarcoxylic anhydrides and mixtures thereof, a diisocyanate compound, dihydroxyl compound, a trihydroxyl compound, a fluoropolymer, and a mineral filler.

Polyamideimide composition

A coated wire that includes an electrical conductor having an abrasion and varnish craze resistant lubricated coating. The coating is made of a ceramic particulate material dispersed in a polyamideimide binder. Ceramic particulate materials suitable for incorporation in the coatings include silicon nitride (Si,N,), aluminum nitride (AlN), and titanium nitride (TiN).
