Powdercoating a Frame(14 posts)

Powdercoating a Framedaniell

I would like to have my beater frame powdercoated. I was thinking of going to a non bicycle powdercoater. Does anyone have experience with such a powdercoater?

Thanks

Yes. I went to a PCer for 2 frames, both steel. Actually I went to 2 PCers. The first guy, I picked out a color and I waited...........stopped back a week later, don't have your powder yet,.....another week, my sprayer is broke, ........another week, my oven is broke and my sprayer is broke, finally the guy tells me he won't do my steel frame as he is afraid that the heat of the oven will damage the frame (350*), he was going to do this for $75.

PCer#2 was a pro shop, not a lamp finisher like #1. He knew his stuff and had nice examples of work. Your PC must be UV safe, otherwise it will quickly fade from sunlight. That being said might raise material price a little. Then the color you select might cause price to rise if they do not carry the powder as a "stock" powder and they have order it. The next problem is quantity, most suppliers sell powder in large quantities, a frame requires about 5lb of powder. PCer will not want to absorb the cost of all that extra powder, (50lb might be a minimum order) but some suppliers will sell small quantities.

Price? stock color, frame prep including fork, $125. Non stock color, $150.

Had a Cannondale frame done this summer. I went to the only place in my town that does powdercoat. They mostly do cars and motorcycles, but I know a framebuilder here in town that uses them as well. My frame came out great. I just made sure to tell them what to tape off. I got a good deal because they had a color very close to the one I wanted left over and only about enough to do a bike frame, so they sold me the powder dirt cheap. I paid $60 for mine to be done. Normally it would have been $100. I then went to a local print shop and had some custom decals printed on mylar, but I have yet to put these on the frame. I like the bare look.

Also, don't worry about it hurting your frame at all, the temp they bake at is too low to do any damage. Especially to a steel frame.

will the powder make a frame heavier like a pound or two?

Talk to Carl Strong at Strong Frames. They will powdercoat other bikes besides Strong bikes and do powdercoat bikes for other companies. They can also tell you how many grams more powdercoat weighs than paint but it's not much.

I have a couple older steel frames that I picked up on Ebay and was thinking of getting them powder coated. What kind of prep work do they do? Do they blast it or something to remove the old paint? The frames I bought have some chips and license stickers on them.

If you go down this path to strip the old finish your frame will have remnants of sand/glass all through it. Lots of detergent, bottle brushes, tube flushing has to be done to get threads and tubes clean. The dust from that kind of stripping can ruin your BB threads. Scrub and flush the heck out of it.

The first frame I had PC'd was a '99 Lemond Zurich. The paint peeled off like cheap tape, frame was still perfect just missing alot of paint from the bottle bosses to the BB. Called Trek. Trek says "sorry, past the warranty date but we can paint it again for $200 plus shipping." "What about PC, will it damage the frame from the heat?" "It will void your warranty if you get it PCd."

Had it powdercoated for $60. Just a local guy who does mostly farm equipment. I had a wide selection of colors but chose this finish because it was so different. He took care of all the prep work too, bead blasted the frame which took off everything, paint, decals, rust, scratches. The curing temp is only about 350 degrees which is well below anything that will hurt a metal frame. Make sure he knows what to tape off before he coats the frame. Powdercoating ain't rocket science. You simply give the frame an electostatic charge so it attracts the very small plastic particles that are sprayed onto it like paint. The frame is then baked to melt the plastic and bond it to the frame.

and finish with a 400 grit. The wipe the frame down with Xylene. Wear gloves and do outside or in good ventalation. Xylene is a very aggressive solvent.

Before this disassemble the bike completely including head set and BB. The baking temperatures are 350-400 and Xylene is hard on seals and anodizing.

Make certain BB and Top tube openings are masked off.

Go to a powdercaoter that uses an electrostatic and then baking process and has some experience with bicycles or motorcycles.

I saw this in their tool catalogue and thought that it was strange there was no oven or electrostatic charge system as optional equipment.

I had visions of building a box to extend my stove oven and curing the frame in the kitchen. I was overtaken with fear when my wife walked by and simultaneously the thought catapulted from my mind never to be mulled over again.

I wonder if a pizza oven would be good. Maybe I should ask my pizza guy whether I could stick a frame in with the pizza.
