powder coating

[wango]

I searched for this but didn't find what I was looking for.

Has anyone tried powder coating stuff themselves and baking it in an old oven? There are powder coating starter kits on ebay for a couple hundred bucks, are they worth a shit? I'm not talking about complete frames or anything, just small parts like brackets, wheels, handlebars, etc.

Read the threads it helps.


Try New levers it helps to have a plasma cutter. They talk about powder coating the levers.

Yeah powder coating is pretty simple....the ones you see on Egay aren't the greatest quality but they get the job done. I'll give you some advice...powder coating is all in the prep work...you have to do a damned good job at prepping the materials you're working on and the work area. I don't recommend doing it in your house or outdoors...but in a well ventilated area if you're just doing a garage type do it yourself kinda shit....

make sure after you blast, grind, sand, etc everything off the material you're prepping that you use some type of metal wash to degrease the materials and have the surface contaminent free....simple instructions can be found on GOOGLE or any search engine found out there.

and yes you can use a conventional household over made by GE or whomever the F*ck and go at it...i wouldn't use the oven to cook in after you've baked your powder coated goods in....

lol, good shit, thanks sassr

I'll keep my eye open for one of those free but still works propane oven that I can throw in the corner of my shop, like I need something else cluttering it up.

[sassr21]

yeah yeah man...make sure the oven that you do get keeps constant temp instead of fluctuating like most conventional ovens do now. you don't want it to heat and cool, heat and cool...want it to bake at the same temp continuously for the recommended amount of time on the powder's canister.

Okay, I'm a dumbass noob. I tried powder coat, coating, diy and a couple others. '' powder coat oven'' was the hit I needed several guys tried it/doing it.
I'm gonna try it.

my dad owns a powder coating business and iv worked with him enuff to know that u can use a house oven but they say once u do dont use it for anything else...everything turns out better if u bake the part first before u coat it...it helps get all the oils and gases out of it...also i recomend hanging all the parts rather then laying them on racks...but if ur lookin to buy a kit get a decent one... he gets all his stuff threw a company called eastwood there pretty reasonable on prices

Thanks pbouey, I'll check em out. Have you or your dad done any two color powder coating on one piece? After you bake the part the first time do you let it cool before coating or coat it while its still hot? I picked up a sand blast cabinet and some walnut shells to blast my aluminum parts with.

[pbouey08]

hey sry it took so long to get back im still not sure how to use this site. iv never done two colors before on the same part before sry man...my guess is that it would leave a thick line between the two colors if you know what i mean...if ur going to try it get some of the clear coat powder to put over the whole thing...id let the part cool between colors so u dont risk them blending but if u are going to b doing aluminum parts bake them first for like 10 or 15 min to get all the gases out of the metal or else it will gas out and leave little like bubbles that was a problem we had for a while. sry i dont have an answer lol

[wango]

Thanks, I haven't checked this in a while myself. I figured it would be tough to do two colors, I think I'll stick to just one for now.

I've had a few things coated. I've spent less having it done professionally than it would have cost to do it myself. In my opinion, if you can find a place local, just have them do it. Much less of a hassle and you are (mostly) guaranteed excellent results.

I had a 7' bumper done for my Jeep for 100$ and the coating lasted for 3 years before it showed any signs of age.

I would probably do that for one or two things, but since my youngest son and I started this project the first week of March my middle son has announced he wants to chop his bike. And now my oldest is telling me he found a '79 Yamaha XS1100 that he's thinking of buying and chopping. So if I can figure out how to do the powder coating thing in my shop, just for small stuff, it should save us alot of cash.

The easiest and best way is to tape off the area then apply your first color, 1/2 cure it, then let it cool just enough to tape it off then shoot your second color, then put it back in the oven for the full bake time on the second color. It'll turn out just the way you want with a sharp line. They won't bleed over. Also if you can find a LOW speed high temp fan to put in the oven and get some air moving you will get much better results. you can google two color powder coating and find tons of info from professionals on the subject. It's one of the easiest things you can do. But like a few others said, bake the part first, then leave it in the oven and turn it off and let it cool in there so outgassing doesn't affect your powder, and don't use the oven for anything involving food EVER again. And prep prep prep. That is 90% of getting great results.

[Rockit]

don't use the oven for anything else EVER again.
Reasoning?

[fearjar]

Reasoning?

I meant don't use it for anything involving food ever again. You can still use the burners to cook just not the oven. The reason is poison. A lot of chemicals get outgassed in there, and you don't want it contaminating your food.

Wrong. One of the advantages of powder is the environmental friendliness of it. There is virtually nothing harmful released from the coating during the curing process. Many industrial powder coat ovens don't even vent to the outside they exchange air directly with the shops work space.

I have worked in every capacity in a very large powder coat job shop. Dealt with the OSHA requirements. I have NO reservations using my kitchen oven to cure small projects.

You put more nasty shit in your oven using oven cleaner.

No shit. I always heard differently. And I know some shops. But they probably want ppl to fear It so they can get the work. So since you're the pro on it what do you think is the best way to do a two color. Because I've done it my way with great results, but if there Is a different way I'd like to hear it. And I'd also like to know what the thickest layer you can lay down. Thanks. Now that I know I can use my oven it gives me the option of doing more. I used a buddies oven when I could get it. But if this ruins my home oven I'll warn you now....My wife will kick both our asses. LOL.

For two color, I've always shot one, bake JUST until gel stage and shoot second. Use clean cloth to wipe my sharp lines. I had trouble with discoloration when I tried taping lines. 95% of what I did was volume production stuff. 10,000 little doodads all the same color. I didn't do very much two color a all.

Maximum optimum thickness varies greatly and depends on the powders formulation, material, particulate size etc. Most polyesters and urethanes (ie. what most people here will be shooting) are normally 2-6 mils. Thicker than that and you will tend to get orange peel. Some special purpose powders, epoxy pipe coating calls for a minimum of 25 mils if I recall correctly.


Don't worry, after a while wives tend to give up and just accept projects. I use oven for powder coating, stove for brewing beer and the bathtub to degrease 4x4 parts. I just clean up well and she no longer cares.

LOL M8. My old lady would shoot me dead. She came home and caught me with my Harley in the dining room putting on an S&S Super E because it was to cold in the garage. Flipped her lid, and it was a tile floor that opens right to the garage.... Still complains about that. But she let me install a wood burning furnace to heat the garage. Might have to go for the oven and see if shell let me buy one of those.

I'm with ya, safe or not, my wife would flip out if I was powder coating stuff in the kitchen. After 22 years, I have a pretty good idea of what will piss her off, and this isn't worth it. Been watching CL and garage sales for a cheap oven, haven't found one yet, but I'm sure one will come along soon.

So what about all the nastiness released from the materials being cooked off? That was always my concern... I really never worried about the powder being harmful...more of all the shit that's in the materials...and yeah I know if you say "well if you prep it good you won't have to worry about that" but there's always areas on items that you're not going to be coating and those areas you don't prep...just a thought.

Just a thought on how you might get a good used oven. I'm a contractor and use to do work for Lowes and independant appliance stores. Often times home owners, especially the wives want new appliances. The old ones work fine they are just outdated. Find the installer for these guys, contact him and you might get a nice used oven for free or dirt cheap. When I was doing installs we just hauled the old appliances back to the store. You just need to explain what you are looking for. There would be nothing worse than going to this trouble only to get a non-working appliance. I've changed out 30+ year old appliances that looked brand new, having said that I have also seen the worst society has to offer 2. Talk to the appliance salesman you might just get a freebie.:idea2:

Hmmmm, my wife is bugging me for a new oven. I may have to look into powder coat tools and let her get one....

[Rockit]

l...more of all the shit that's in the materials...

You mean contaminates in the substrate? You do get slight off gassing is some instances but I think the risks of that are minimal at worst. Most likely insignificant. Any significant contamination leads to serious blemishes in the finished surface.

I would guess you expose yourself to more harmful chemicals using lighter fluid on a bbq than the occasional powder project cured in an oven.

[sinisterspirit]

I would imagine that the oven cleaner that you spray into your oven would be more toxic than what comes off of you powder coating project.

[shadow phoenix]

hmmm i have my own powder coating set up but i was told to only use electric ovens and not gas cause reaction of powder could ignite. noyt for sure about that but just a pre causion. i got my kit from harbor freight tools and it works o.k. but your final product reflects the prep job so do a good job before you coat it.

[bandit]

We have a powder coating gun and oven at work I powder coat shit all the time. Nothing hard about it.
