“As far as I know, the electrostatic painting of a plastic requires that the paint and plastic have opposite electrical charges. I want to know if and how I can electrostatically charge a plastic?”


“Since both the paint and plastic are dielectrics, electrostatic charging can be used. However, the results will be dubious since the charges may cancel each other out. This would result in no powder being deposited on the surface. Normally powder coating is applied to grounded conductive products (metal) using electrostatically charged powder particles. Powder coating plastic has been performed in the past using thermal attraction; the plastic part is preheated and powder is sprayed using typical electrostatic techniques. The heat enhances the adhesion of the coating particles on the plastic surface.”
