Not All Metals Can Be Powder Coated

Powder coating is a popular alternative to liquid painting that looks great on automotive and motorcycle parts, patio furniture, staircases and so many other items in need of restoration. This painting process is known for forming a great finish on metal surfaces. However, contrary to popular belief, powdered paint can’t be applied to all types of metal. If you’re looking for a powder coating shop in Washington, it’s good to learn which kinds of metals can thrive with a coat of powdered paint and which metals should be painted with an alternative method.

Metals That Can Be Powder Coated

The fine powder used in this painting method is electrostatically charged, which is what attracts it to metal surfaces prior to the curing process. If a metal or material can’t hold an electrostatic charge, the powder won’t be able to affix itself to the surface, and it won’t be able to be powder coated. Additionally, a metal will need to be able to withstand the high temperature levels that are used during the curing process in order to be a good candidate for powdered painting. Here are some metals that receive great results after this refinishing process:

  • Aluminum
  • Stainless steel
  • Mild steel
  • Galvanized steel
  • Electroplated steel
  • Steel alloys

Metals That Can’t Be Powder Coated

While most metals are good candidates for powdered painting, there are a few that pose a problem. Some automotive parts are made using plastic or resin body fillers, which creates a problem for two reasons. These metals typically won’t allow the fine powder to stick to their surface, as they aren’t electrostatically charged. Additionally, the plastic or resin body fillers can’t withstand the high temperatures required during the curing process, often causing bubbles and other imperfections to ruin the finish. Other materials that can’t be powder coated include rubber, plastic, wood and anything else that melts at high temperatures.

The Condition of the Metal

In order to qualify for powder coating, the metal or material you’re working with doesn’t have to be new or in perfect condition, but it will need to be prepped. Aside from it being cleaned, it should also be sanded in order to remove any dirt, rust and any other elements that will affect the end result. This includes getting rid of any signs of the metal’s previous finish. As long as it’s prepared properly, your powdered painting results will be fabulous.
