Corrosion of Powder Coated CRCA Panels: Critical Protection

Summary for corrosion of powder coated crca panels Discussion

The focus keyphrase, corrosion of powder coated CRCA panels, is really about how to protect dull powder-coated CRCA panels when they are exposed to acid fumes. In the thread excerpt, Jeetendra Makkar asks how to prevent corrosion in these panels, but no detailed answer is shown in the source provided. Because the excerpt contains only the question and site navigation text, there is no named technical recommendation to summarize beyond the problem statement itself. The practical takeaway is that the panels are being challenged by an acid-fume environment, so any solution would need to address chemical resistance of the coating system and exposure control. Since no answer text is included, no specific method, product, or process can be attributed from this excerpt.

A. Hi JEETENDRA. An epoxy powder coating on top of proper zinc phosphatizing is probably the best you’ll do with a sprayed thermosetting powder. May we assume UV-resistance is not required? Although nylon is not truly acid-resistant, a heavy fluidized-bed application of thermoplastic nylon should far well in mildly acidic situations.

If you need true acid resistance you probably would need plastisol coating.
