Do you know of any type of body filler (putty, fiberglass, bondo) that powder will stick to?
I run a powder coating line and apply powder manually using a box feed system. It is baked on with a conventional gas flame oven. Hopefully you can help me out. There are some filler materials currently available for repair of substrates to be powder coated. The repairs that can be touched up with these fillers are pits, voids, scratches, etc. The fillers are typically applied by use of a spreader or spatula, then are either air-cured or oven cured. You would have to check with the manufacturer of these products to determine their electrical conductivity and if the fillers meet the specifications that you are looking for. I’m sure that the manufacturers of these products would encourage testing before committing to the use of fillers in a production environment. Here are a few supplier suggestions with phone numbers and URL addresses to help get you started. • Alvin Products offers Lab Metal.
