Powder coating

[B.G. Smith]

I have a headache rack that is black "powder coated". I need to do some mods on it (welding) and would like to know what material is used to powder coat? bg

You will have to get the rack all fabbed up just how you like it then take it in to be powder coated again, the powder coating process is different than just spray paint, they take an electrical charge to the item needing painted and then release the paint into the room and it sticks like glue to the metal, then a baking process after that... ... ... . tough as nails.



anyway thats the way my dude does it.



Cheers, Kevin

Thanks Kevin, I suspected that. I will probably be better off to just buy a new one. The mounting on the one I have is just not sturdy enough. bg

You can buy your own kit:

The application process is simple enough it is the oven that is the hard part. The home kits are designed such that you put the parts in your kitchen oven. I don't think a pick-up rack would fit.

plastic

Plastic, that right, came from the powder coaters today and learned that the product is plastic. After sandblasting the iron is charged which opens up the pores in the metal and the plastic flows into the pores. After the flowing, the heated metal closes the pores on the metal baking the plastic solid. Pretty bazar, I thought. Got this from Portland Powder Coaters. Tim

There are different powders. We have an epoxy powder coat line where I work. Black. We paint our steering intermeduiate shafts with epoxy because they are in the engine compartment and can see high temps ... around 400 F. The curing temperature we use is 250 F.

The epoxy will not hold up well un a UV test, but since our part is in the engine compartment that's ok.

For UV resistance we would need a polyurethane powder. , which is probably what Tim was referring to. That is a totally different process as far as materials, processing temps, curing, etc.

The two types are not compatable. All the opposite type of material would have to be fully purged from the system, and all the process parameters changed... not practical in our set-up, but could be possible for a small job shop.



There... I was able to fill a postage stamp with all my powder coating knowledge.
