Abstract
Objects which have been abraded are coated with a coating material which is normally solid at room temperatures. The material is liquified at elevated temperatures and sprayed onto the cooler objects in a heated cabinet, whereupon the material at least partially solidifies on the object. Thereafter, heat is applied to the coating material to cause it to flow out over the coat surface. A cooled conveyor system prevents disruption of the coating material. Overspray is maintained in liquified form within the cabinet where it is reclaimed and flows to a heated sump for direct recirculation to the spray apparatus. There are no deleterious solvent emissions. Apparatus and methods are provided.
