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

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.
