“I am using brushed aluminum in an outdoor environment. Can bare aluminum be powder coated clear, and if so, how long can I expect such a coating to endure outdoors? Is there a powder formula that you would recommend for such an application?”


“To powder coat aluminum, you must have a completely clean surface. Normally aluminum has some oxides on the surface that can cause problems with adhesion and corrosion protection after coating the substrate with powder. These soils must be removed for the powder coating to provide maximum protection and excellent clarity through the coating. Fluoride in solution is normally used for this purpose. Review your specific requirements with a knowledgeable pretreatment chemical supplier for further information.”
