What materials can be powder coated?

The parts must be electrically conductive therefore the majority of parts and assemblies we coat are made of metal. Heat curing is required to form the final finish with powder coatings, as such the part must be able to withstand typical curing temperatures ranging from 250°F to 450°F. However, new curing technologies and low-cure powders are becoming available for heat-sensitive substrates such as conductive plastics and assembled products with heat-sensitive components.
