The Condition of the Metal
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.
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.
