Inhance/Fluoro-Seal Ltd. (Houston, Texas) and Finishes Unlimited (Sugar Grove, Ill.) have jointly developed INFIN Coating Technology, a two-stage inline process that applies a decorative yet functional topcoat to extruded wood plastic composites (WPCs). Reportedly, the coating is available in virtually any color and resists fading, heat retention, mold, mildew, stains and abrasion. The technology first passes the WPC through a pretreatment chamber, where it is exposed to a reactive gas that oxidizes the surface, altering its molecular structure to optimize adhesion with the subsequently applied, proprietary UV-curable coating (pat. pend.). The coating is applied in a second chamber where it is instantly cured under UV lamps. The VOC- and HAP-free process can coat composites at speeds of up to 200 ft/min (61 m/min) and can be installed as a standalone system or integrated into a WPC line.
