PTFE powder coating can make machine parts corrosion-resistant
A service for applying PTFE (polytetrafluoroethylene) powder coatings to chemical processing equipment is now being offered by this company. The coating is designed for all types of parts, from small components to large castings, that require chemical and corrosion resistance. The coatings can be tailored to customer requirements, and involve an electrostatic application process that can apply PTFE at thicknesses between 0.0002 and 0.025 in. The service is suitable for single parts or high-quantity production runs, and includes proper surface preparation and subsequent baking to ensure a uniform finish that resists abrasion, chemical attack, corrosion and mechanical damage. Typical equipment for the service include valves, pumps, mixers, chutes, tanks and handles. — Applied Plastics Co., Norwood, Mass.
