Abstract: The present invention relates to a substrate having (a) a first material applied to at least a portion of the substrate, and (b) a coating layer deposited from a powder coating composition including a film-forming resin, and optionally a thermally conductive, electrically insulative filler material and/or a crosslinker that is reactive with the film-forming resin, in direct contact with at least a portion of the substrate to which the first material has been applied. 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.

Abstract: Disclosed herein are systems for treating a substrate. The system may include a cleaner composition, a deoxidizing composition comprising a Group IVA metal and/or a Group IVB metal and free fluoride and having a pH of 1.0 to 3.0, and/or a seal composition. The system may also include a coating composition. The cleaner composition, deoxidizing composition, and/or seal composition may comprise a homopolymer or a copolymer comprising a phosphorous-containing monomeric subunit m1. Also disclosed is a deoxidizing composition comprising a Group IVA metal and a Group IVB metal and free fluoride and having a pH of 1.0 to 3.0. Also disclosed are methods of treating a substrate. Also disclosed are treated substrates.

Abstract: Disclosed herein is a composition comprising: an epoxy-containing component, elastomeric particles in an amount of greater than 11% by weight to 25% by weight based on total weight of the composition; and a curing component activatable by an external energy source, the curing component comprising at least one guanidine having a D90 particle size of 25 μm measured by dynamic light scattering. Also disclosed is the composition in an at least partially cured state. Also disclosed is a method for treating a substrate comprising applying the composition to a surface of a substrate; and applying an external energy source to cure the composition. Also disclosed are substrates comprising the composition. Also disclosed are substrates formed by the method of the present invention.
