Title: Powder coat DIY
Post by DangMan on 06/01/11 at 14:58:33

After yet another time realising what lame part of the world I lived in, I realised that if I should have a go at a powder coat setup I had to do it my self ! :D

I searched around the interned for a while and got inspiration, thereafter I used a couple of days scavenging parts.

Here is what my first testrun resultet in this evening !

First of all here is the gun, I know its a bad quality of pix, but ill make some btter soon ! ;D

First try at a "dummy" Im pretty proud of the result, but I think there is a few things to tweak before "im there"

I was not realy satisfied with the way the powder clinged on to the metal and figured that the 4kv transformer is to small, so now im waiting for a 15kv transformer MORE POWER :D

What brand gun is it ?
And what powder did you use ?

I bought a Craftsman gun (airless) not long ago, and some HF matt black powder. It works great in warmer dry weather, but I have trouble getting the powder to stick in cold hi humidity weather. And thats all we've had the last couple months here.
I don't know if some different powder would work better, but the HF powder is cheap cheap compared to other powders.
This just a sample of some non blasted parts I've coated so far, look great,......if you like matt black. :o

How well is the paint sticking to the parts? If this is a "test part" put a piece of duct tape on the painted surface. Make sure it's on there good and tight. Then rapidly pull the tape off the part. if all the paint stays on the part and not on the tape you have an excellant paint job.

For the generator I used this one and took the generator !

I took a look in the phonebook and found a firm that powder coated pro. Called them up and asked if I could buy a little powder. He was incredible nice and before I left the firm I got a ton of good advise and best of all, 3kg pro powder for 10$

I just wiped the wrench of with degreaser and hooked it up. After baking the paint sticks REALYREALY good. Eaventhough its my first try at powder coating I dont think I have made ass well a job with a rattle can.
I had to take a pointy screwdriver to even make a scratch !
I used a conventional oven for baking, 180C for about 25 min !

Im still waiting for a better generator, but ill keep on posting as I go !

Yea, heat gun, that would work. Wonder if it would stink up my basement. I want to do my wheels red, winter project for next riding season with white wall tires.

I can't imagine ever getting the powder coat to come off. I didn't sandblast the parts, just cleaned them w/ wire brush and w/ Laquer thinner. And that powder is as strong as the surface its attached to. And let me tell you, that hot rolled scale is as tough as iron.

I do the parts in a convection oven heated to 400 degrees.

Tryed stress testing the paint today ! Tough stuff ! Had to use a pointy hammer to get small plakes to come of and even after that I could not widen the damage trying to rub more of with my nail !
