Question:

I want to use powder paints instead of liquid paints. I can get a small hobbyist powder paint process for less than $100.00. Since I am new to this whole process, I would like to know if every powder coating need heat to cure it? I have a small oven for most of my parts, but the large parts will not fit in it. A. S.

Answer:

All thermosetting powder coatings must be heated to at least 250F to melt them onto the part surface. Full cure is then achieved either using UV energy or heat energy (> 250F). If you are a hobbyist, forget about the UV systems and low temperature cure powders and plan on heating your parts to 350 – 375F for 10-20 minutes. If your parts don’t fit in your oven, buy a bigger oven or call one of the 10,000 custom powder coaters in the USA to do the work for you.
