Powder coating conductive high-heat-resistant plastic parts on the same line with metal parts
Plastics are used for a variety of parts from mobile telephones to automotive body panels. However, powder coating has not been the finish of choice primarily because of the challenges involved in the non-conductivity and temperature resistance of these materials. That is about to change. This article discusses a new plastic resin that is not only conductive, but also heat resistant to more than 400 degrees F. The article discusses how this development will now allow powder coaters to finish both plastic and metal parts on the same line.
Powder coating is a fast-growing technology due mainly to its environmental benefits, particularly the elimination of solvents and related compounds that are emitted into the air in conventional liquid paint. Powder coating has traditionally been used with metal substrates; however, the need for greater design freedom has led to industry demand for technologies suitable for plastic substrates.
