Question: I want to use powder paints instead of liquid paints.


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.


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.
