Abstract: A coil coating system for embedding discrete masses of material in a resinous coating on sheet metal as it is pulled from a dispensing coil through a series of rollers, said system comprising a paint pan, a roller rotating in the pan and picking up said resinous coating composition and transferring it to an applicator roller; thenceforth to the moving sheet metal, an oven, and a sprayer that can heat thermoplastic resin particles to a molten or plastic state and spray the particles to the moving sheet metal.

Abstract: This invention relates to a method for embedding a multiplicity of discrete masses of material in a resinous coating on a sheet of metal in a coil coating system. The sheet is coated, the masses are embedded in the wet resinous coating, and the coating is dried in a one-pass system. The resinous coating and the embedded masses are preferably resistant to ultra-violet radiation. The wet resinous coating, therefore, is preferably a liquid fluorocarbon resin. The discrete masses comprise pigmented particulate minerals and resins in the form of granules, beads, vesiculated beads, pellets, flakes, platelets, cylinders, coating powders, and coating powder precursor chips. The minerals include glass, quartz, mica, pebbles, and ceramics. The particulate resins include polyesters, acrylics, nylons, polyurethanes, polycarbonates, solid fluorocarbon resins, and solid mixtures of a fluorocarbon resin and an acrylate or methacrylate polymer or copolymer.
