THE RECENT ADVANCES IN THE USE OF PLASTICS IN THE AUTOMOTIVE INDUSTRY HAS PROVIDED INCENTIVE FOR COATING MANUFACTURERS TO LOOK AT NEW AND INNOVATIVE METHODS FOR PAINTING PLASTICS TO PROVIDE DECORATIVE AND PROTECTIVE FINISHES. ONE SUCH METHOD, IN-MOLD COATINGS, HAS BEEN SHOWN TO BE A VIABLE AND EFFECTIVE PROCESS FOR PAINTING POLYURETHANE RIM PLASTICS. THIS PAPER DISCUSSES THE PROCESS, COATINGS, AND PRESENTS USES BOTH IN AUTOMOTIVE AND RELATED INDUSTRIES. COSTS AND THE PROSPECTS FOR THE FUTURE OF THIS TECHNOLOGY ARE ALSO DISCUSSED. A BRIEF HISTORY OF THE DEVELOPMENT OF IN-MOLD COATINGS AND THE CHEMISTRY OF THE SYSTEMS IS PRESENTED AS BACKGROUND.
