Paint for centrifuge

[Jens]

My veggy oil centrifuge is gradually coming together and soon it will be time for paint prep (body filler) and then a coat of paint.
I wish to only paint this contraption once so I wonder if anyone has suggestions what kind of paint to use. This paint will go on the outside of the chassis and all parts but it will also go into the inside areas. These areas will be under constant impact from veg oil or motor oil and I would really hate to see the paint blister up and peel off.

I am thinking that powder coating might be a good idea but I am not sure what kind of powder formulation I should ask for. I also do not know what kind of body filler could be used that is motor oil resistant, veg oil resistant and that can work with powdercoating and the heat of curing a powder coat.

Would an epoxy paint be more durable than powder coating ?

Any suggestions would be greatly appreciated.

Por15 is supposed to be some of the toughest stuff out there but rather pricey. I have a small can but never used it.

I am not that impressed with por15.  And I was por after I bought it (the second time).  Never, NEVER, never paint directly out of the can.  Always close the lid immediately after pouring out what you need.  Don't even think about poring excess back into the original container.  Dampness is it's catalyst.  And it must be protected from UV – sunshine.

what about the fired on ceramic coatings for headers?   Hot rod shops & mail order can do them.

NAPA, sells a ceramic spray bomb, including primer. It's rated at 1000 F. It doesn't have to be baked, but it improves the end results...just the heat of the machine will bake it over time.

I painted both of my perkins diesels, and associated parts....trannys, v-drives, and all brackets, with it 9 years ago...it looks as new, today.

I set up a bake booth, it was made of blue r-foam 2 inch insulation, basically a large box, with top. Then I set inside the box in each corner a 2 headed 500 watt halogen work lights, a total of 4000 watts of heat.

I baked for 24 hrs....I didn't measure the temp in the box...but I guessing it was some near 150 f.

if you use por15, use a piece of cellophane wrap to cover the can before you replace the lid
if you don't you likely will never get the lid back off again, even if you have not spilled any into the groove
in the can.

if you spill into the groove and don't use some plastic wrap, you may as well figure on punching a hole in the can to
get the remaining contents out again.

for what it was made to do, it does well.

i am not sure i would paint the inside of a centrifuge, seems like no matter what you use eventually the tiny particles are going
to wear the paint away.

As Bob said - if it ain't part of the design, it can't fail.  KISS in action.
