Abstract: A method of coating a substrate includes the steps of: (i)providing a suspension of dye and a binder in a solvent, wherein the ratio of dye to binder is greater than 40 wt% and the dye is uniformly dispersed in the solvent; (ii)spray-coating the suspension onto the substrate with the majority of the solvent evaporating during the spray coating step to result in a coating of dye and binder on the substrate having a density of up to 0.75gcm-3; and (iii)continuing step (ii) until the coating thickness is at least 30 micrometres; wherein the dye does not include any carbon nanotubes.

Abstract: The present invention relates to a method for producing a composite part comprising a textured skin and a rigid or foam substrate layer, in particular a composite automotive trim part. The method comprises the steps of spraying or casting an aqueous thermoplastic dispersion onto a rigid or foam substrate composite followed by forming the composite into a composite part comprising a textured skin and a rigid or foam substrate layer. Preferably, the dispersion is derived from the extrusion melt blending of thermoplastic polymer, a dispersing agent, and water.
