  • Valve cover having a gelled powder coating on the raised surfaces of the valve cover
    Patent number: 6190745
    Abstract: A product made by the process for powder coating selected portions of a substrate comprises the steps of electrostatically applying a controlled thickness of a powder to an entire surface of a transfer member to form a powder coating thereon, the powder having a gel point, the temperature at which the powder turns into a gel, heating a substrate to a temperature above the gel point of the powder, pressing the heated substrate against the powder coating of the transfer member to melt the powder coating on the transfer member and cause the melted powder to stick to the substrate and coat selected portions of the substrate, and polymerizing and curing the coated portions of the substrate to fix the melted powder to the substrate.
