UV curing is used on interior parts such as consoles, door components, dashboard instrument panels and displays, touch screens, and control buttons and knobs. UV coatings provide durability, scratch resistance, and a range of aesthetics including soft-touch, gloss and matte finishes with excellent adhesion on plastic parts.
Waterborne UV-curable clearcoat provides excellent mar and chemical resistance as a very low gloss coating on flexible vinyl-wrapped parts. The UV coating provides higher performance than solvent-borne and waterborne thermally cured coatings, with a very low VOC content.
In-mold films with latent UV activation are also being used to decorate interior automotive trim. These in-mold films are used to decorate the trim in high pressure injection molding processes. Post mold, the parts run through a UV curing process to activate the high performance properties common to all UV coatings. This process is commonly used for consoles and other interior parts, especially on high-touch surfaces that require high abrasion resistance such as door trim, consoles, and radio surrounds. Finishes available are piano black, carbon fiber look, and more recently, soft touch films are available. UV curing provides improved throughput and aesthetics compared to post-paint coating.
Markings on instrument panels, gauges, and control knobs and buttons use UV-curable inks because they provide improved durability with reduced VOCs compared to traditional inks. Chrome look plastic parts are using UV cured primers and topcoats for PVD processes which are environmentally friendly and provide durability and recyclability of interior parts such as door handles, brand badges, and consoles.
