Abstract: The present invention is directed to a solvent borne low bake curable coating composition having improved sag resistance and coatings properties and process for using the same. The composition includes a crosslinkable component having one or more polymers having two or more crosslinkable groups, a crosslinking component comprising one or more crosslinking agents having crosslinking groups; and a low bake temperature control agent that includes a rheology component and polyurea. When a layer of a pot mix resulting from mixing of the crosslinkable and crosslinking components is applied over a substrate, it has high sag resistance while providing desired coating properties, such as high gloss and rapid cure even under low bake cure conditions. The solvent borne coating compositions is well suited for use in automotive refinish applications as well as industrial applications, such as construction and transportation equipment.

Abstract: A crosslinked coating composition formed from polyurethane polyols and blocked or unblocked polyisocyanates. The polyisocyanates, in particular, comprise at least bis(isocyanatomethyl)cyclohexane. The coating is substantially free from ester functionality that forms a contiguous part of the network backbone. A clearcoat formed from the described components and having a majority of urethane bonds is very resistant to environmental etch damage.

Abstract: The present disclosure is directed to a coating composition that is capable of producing coatings being sag-free at high coating thicknesses, having excellent adhesion to substrates, and good appearance. This disclosure is further directed to a coating composition comprising components derived from renewable resources.

Abstract: This invention relates to a method for forming a multi-layer coating on a vehicle body, comprised of applying primer coating, base coating, and clear coat layers in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer layer comprises a film-forming binder comprising two acrylic polymers, the first being a caprolactone-modified branched acrylic polymer and the second being a caprolactone-modified linear acrylic polymer; and a crosslinking agent selected from aminoplast resin, blocked polyisocyanates, or mixtures thereof, wherein the composition is, essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both. The resulting multi-layered coating has excellent aesthetic appearance, strike-in resistance, chipping resistance, sag resistance, and film build even when formed in a three wet layered application method.
