NOVELTY - A substrate comprises (a) a first material applied to greater than or equal to 1 portion of the substrate; and (b) continuous film deposited from curable powder coating composition comprising a film-forming resin having functional groups, a thermally conductive, electrically insulative filler material, and optionally a crosslinker that is reactive with functional groups of the film-forming resin, in contact with greater than or equal to 1 portion of substrate to which the first material has been applied, where the first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier; and optional (c) poly-carboxylic acid functional (meth)acrylate polymer reactive with the epoxy functional polymer. USE - A substrate e.g., fastener, coiled metal, a vehicle, a package, a heat exchanger, a vent, an extrusion, roofing, flooring, a wheel, a grate, a belt, a conveyor, an aircraft, an aircraft component, a vessel, a marine component, a vehicle, a building, an electrical component, a grain or seed silo, wire mesh, a screen or grid, a frame, a tank, a cord, a wire, a battery, and/or battery component (all claimed). ADVANTAGE - The substrate has decreased sag resistance, improved adhesion, improved edge coverage, improved thermal conductivity, and/or dielectric properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for treating a substrate which involves (a) contacting greater than or equal to 1 portion of the substrate with a first material; (b) directly contacting greater than or equal to 1 portion of the substrate in contact with the first material with a powder coating composition comprising a film-forming resin having functional groups, a thermally conductive, electrically insulative material, and optionally a crosslinker that is reactive with the functional groups of the film-forming resin, and (c) liquidizing the powder coating composition to form a continuous film of the powder coating composition on the substrate, where the first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier.
