A special type of powder coating, thermoplastic coating involves the application of a medium-density plastic layer onto the surface of the metal as a decorative or protective coating for steel and other metal parts. Thermoplastic coatings do not set when heated, and can therefore be repaired in heat.
Plastic coating produces a thicker finish than standard powder coating, and can be applied in thicknesses of over 200 microns. This makes it an ideal coating for signs and supermarket trolleys. Thermoplastic coatings can be made from polyethylene, nylon, PVC or other formulations for increased UV resistance. DECO also offers Plascoat PPA 571, a performance polymer alloy coating for increased corrosion resistance in steel.
Thermoplastic coating can be applied by spraying, electrostatically (similar to standard powder coating) or fluid bed application.
DECO can coat almost any size of product, although fluid bed applications may be size restrictive.
Theoretically, products can be plastic coated in almost any colour. DECO stocks green, blue, black, white, red and yellow plastics, however other colours can be ordered in large quantities if you have a large order/batch. See Plascoat PPA 571 Brochure for more colour options.
Thermoplastic coating thickness can achieve thicknesses greater than 200 microns. Plastic coatings are not generally very hard, although harder coatings can be achieved with nylon plastics.
Thermoplastic coatings generally show very good wear resistance, although this is subject to the type of plastic used. In the event of wear, melting and resetting the plastic can repair the coating. Thermoplastic coating melts at around 150 – 200 degrees Celsius and scars on the surface can easily be healed with a hot air gun.
Thermoplastic coatings generally have excellent corrosion resistance subject to the type of plastic used. They usually stand up well to chemicals and solvents.
