Solvent-borne coating compositions and methods for forming coated substrates are provided. In one example, a solvent-borne coating composition includes a solvent(s), a colorant(s), a binder including one or more resins, a sag control agent, and a wax dispersion. The sag control agent includes urea crystals that are present in an amount of from about 0.5 wt. % to about 6 wt. % based on the weight of the binder. The wax dispersion includes ethylene vinyl acetate-based wax particles present in an amount of from about 3 wt. % to about 8 wt. % based on the weight of the binder. The solvent-borne coating composition has a non-volatile content of from about 11 to about 30 vol. % based on the volume of the solvent-borne coating composition.

Coating compositions including a sag control agent and wax

Sag control compositions, methods of forming sag control compositions, and methods of forming coating systems that include at least one coating layer including urea crystals of such sag control compositions are provided herein. In an embodiment, a sag control composition includes urea crystals and a non-polymeric organic solvent. The urea crystals include the reaction product of a polyisocyanate and a mono-amine. The sag control composition is a stable mixture with a single phase at a temperature of about 21&#xb0; C. based upon visual observation for a period of at least 10 minutes after forming the mixture.

Sag control compositions, methods of forming the same, and methods of forming coating systems using the same

The present disclosure is directed to a method of applying at least one layer of a waterborne primer composition, at least one layer of a waterborne basecoat composition and at least one layer of a clearcoat composition to a substrate followed by a heating step which simultaneously cures the applied layers of coating composition.

Method for forming a multilayer coating

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.

Etch resistant clearcoat

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.

High film build coating composition containing polytrimethylene ether diol

This invention is directed to a coating composition comprising an coating composition comprising a crosslinkable composition and a crosslinking composition. The crosslinkable composition comprises an acrylic polyol wherein the acrylic polyol comprises at least 40 percent by weight of at least one linear or branched C8 or higher alkyl acrylate monomer and at least one polyester extended acrylate monomer. The coating composition is suitable for use as a basecoat and can be used in a 3-wet paint process that eliminates the primer curing booth.

Acrylic polyol coating composition

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.

Method of forming multi-layer coating on automobile bodies without a primer bake

This invention relates to a method for forming a multi-layer coating, comprising sequentially applying a layer of primer coating composition, a layer of base coat composition, and a layer of clear coat composition on an automotive substrate in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step. The primer surfacer comprises a film forming binder, a volatile organic liquid carrier, and pigment(s); and the binder contains about (a) 40 to 95% by weight of a caprolactone-modified highly branched acrylic polymer having a hydroxyl and/or carboxyl monomer content, all or part of which has been reacted with caprolactone, of about 1 to 65% by weight and a weight average molecular weight of about 10,000 to 150,000; and (b) 5 to 60% by weight of an aminoplast resin crosslinking agent. The composition is essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both. The resulting cured 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.
