Original equipment manufacturers (OEMs) have a strong desire to explore alternatives to coatings. Coatings or paints are generally pigmented polymeric dispersions or powders that are usually applied as a secondary process step to form a layer on the substrate. Eliminating coatings can drastically reduce the cost of the part as well as provide environmental advantages. In recent years there have been major advances in alternatives to coatings for automotive plastic parts. These advances are categorized into two main areas, material development and process development. From a materials perspective, new colorants and modifiers have been developed as additives to plastic resins that provide the aesthetic and physical and chemical properties required. From a process perspective, advances in process technology in areas of extrusion, co- extrusion, injection molding, laminating films, and thermoforming of multiplayer sheets have been developed. This paper will examine these different alternatives to coatings for automotive plastic applications.
