Powder Coating With High Ozone Resistance

Q. Is there any paint/powder coating which can resist high ozone concentrations (of the order of 300ppm (650mg per meter cube)) available in the market? Please name any manufacturer dealing with the above.

A. It is quite possible that there is such a coating, but I'm not aware of it. Have you tried polyurethanes, or polyester TGIC? You might want to send an email to the major powder coating manufacturers, such as Morton, PPG, HB Fuller, and others.
