Decorating a plastic component by plasma treatment and coating with curable resin

At least part of the exterior surface 12 of the component 10 is treated with an atmospheric pressure air plasma (APAP) nozzle 20. The treated surface is coated with a resin, which is then cured (or polymerised). Preferably the nozzle 22 and a sensor 32 are mounted on a robotic arm 30, which moves pl...

Summary:At least part of the exterior surface 12 of the component 10 is treated with an atmospheric pressure air plasma (APAP) nozzle 20. The treated surface is coated with a resin, which is then cured (or polymerised). Preferably the nozzle 22 and a sensor 32 are mounted on a robotic arm 30, which moves plasma jet 22. The component 10 may be mounted on a trolley 16. Exemplified substrates include polyolefin, ABS, polyester, polyurethane and polycarbonate. The cured resin may be a primer, adhesive or paint, optionally coated with a base, top or clear coat. The component may be trim, especially a bumper facia or instrument panel.
