Q. We’re building a part that we expect will be exposed to temperatures above 600°F for extended periods of time. Is there a powder coating that can take that kind of temperature? B.A.
A. Yes, there are powder formulas that can take up to around 1,000°F. Most of these formulas have silicone content. They come in a limited number of colors like black and green. Contact a few suppliers and tell them what you need. You should be able to find something that will work.
