Mobile Powder Coating Without an Oven?? IT WORKED!!

- We tried something a bit different here for one of our customers; mobile oven-less powder coating. There is an actual process known as flame coating for this exact situation which uses a specific kind of powder and application gun, however we had to work within the constraints we had. These beams are too large to fit in our oven at the shop so we had to get creative. Turns out it worked better than we all thought it would.

The reason it worked so well was because it was thick. The steel holds temp for a long time after heating it, so it kept curing well after it was sprayed. Not going to lie, I thought it was some hacks, until I saw your gun. haha
As a roofer for many years and having a couple roof torches kicking around a powder coat system with lbs and pounds of powder. I think it's time to sandblast my truck frame again and give it some powder. All other parts have been powder coated in a small oven but I am definitely going to try this on my frame, inner fenders and possibly the firewall of the truck as well as the inside of the cab and underneath the box 👍
Im not sure if youve started this, but just be aware it might not cure fully or properly, so the powdercoating might eventually fail in some places, leaving exposed metal which could lead to rust issues. Just wanted to give you a heads up incase you werent aware.
I'm curious if thinner metal can hold enough heat, long enough to cure at all?
As long as pretreatment has been done, and your substrate stays hot enough for long enough, you should have good adhesion/cure. Thanks for posting!
Awesome results. Great job to you and your crew. Thanks for the content.
I had thought about it but I didn't think it would have such good results. Great job !!!
Thank you very much for the video. I often wondered if this method would work for curing powder coat on large steel fabrication. Most of the stuff that I would like to have powder coated, are the size of a car trailer finding someone with a large enough oven is it near impossible or very expensive. Preheating it and letting the powder coat cure. You guys did all those metal beams all it takes is torches and heat guns and monitoring the temperature before you lay the powder coat.
You make it look so easy
I wonder if i could use this technique in my motorbike frame. That looks awesome dude
Really interesting 👍
Thinking now do some of this at home.
Cheers
Hot flocking. Well done turned out pretty amazing.
well done lads
Very impressive
Wow, that worked well. I wonder if I could pull off something similar with my home gamer gun.
Bad azz🔥🔥🔥
as wet as that goes on you might be the first ever to get runs in your powder coat
Is First Person Powdercoating a game yet?
How hot was the metal?
I know that diesel heaters will leave residue on the surface.
As long as the metal stayed at the correct temperature long enough, it should be ok. Most powders I've dealt with have to baked anywhere from 350 degrees to 400 for 10 minutes up to 20 minutes. I don't know the kind of powder you guys used nor even heard of this method to be honest. I also would've went the extra mile and sanded on the metal with a DA sander and at least 180 grit sandpaper so the powder has something a little more to bite on to, but that's just me. I hate redoing a powder job due to defects or the customer complains about the quality
Yeah we had thought about adhesion as well. In this case we had the customer wirewheel all the welded areas and use a mild fiber pad to scuff before we started shooting the powder. For any other parts we process in-house we use an 80 grit oxide blast to give the substrate tooth for the powder to adhere to
Looks fine, only problem is its NOT cured / Crosslinked unless you sprayed a NYLON...........
how has that held up?
how much powder coating machine
Ive done the same thing bro.
Did you do a MEK rub test to make sure the powder coating is fully cured?
I doubt they did. That piece is clearly under cured. There’s no way the part held temperature long enough to properly cure.
We had done a mill spec scratch test once the parts were cured, under the middle foot of the beam. I have a DeFelsco eddy current thickness gauge I do part inspection with and this coating was thicker than we usually apply nearing the 8 mil range. Obviously with hot flocking there's a ton of variance but we saw between 3 to 8 mil across the test points on each beam. We have had mixed results using a MEK test on hybrid epoxy powders, this particular powder we used had a very high chemical resistance so I usually stick to the scratch test. That's just my experience. I've had good results using the MEK test on standard polyester and urethane based powders.
How is it holding after a few months?
It's been in service for a while now, they aren't exposed to extreme elements they are used as sub floor supports for an electronics clean room. Controlled atmosphere environment so best case situation. They look beautiful so far.
That is so sketch you gonna blow yourselves up. At least the doors are open and they have a fan.
That shit is going to chip off
im a powder coater you know you could have blew up right?
Really? Cause the powder seeing an open flame?
