Anodizing Specific for Powder Top Coat


We are looking to provide a powder coated aluminum product with superior long term corrosion protection. A possible option we have seen some general comments on is using a base coat of a specific type of anodizing that has excellent adhesion to a powder top coat. I have seen some reference to this as in use in Europe on architectural aluminum. Does anyone have knowledge of the specifics of this combination - and its pluses and minuses ?

Greetings Jeff - Most anodizing will provide both excellent corrosion protection and a superior base for subsequent finishing steps (paint, powder coat, etc.). Vic Waldman

Powder coating and anodizing are like bread and butter. For aluminum, most any anodize will give excellent adhesion to the top coat and protect against corrosion if the top coat is broken.
