Has anyone figured out what powder coating adds to the weight of a wheel?

I'm picking up a new set of wheels that I am considering having powder coated. I don't know if it would add a few ounces or a pound and a half a wheel.

For anyone that has data (not speculation), please chime in...

 

you must be building a serious time attack car, lol

 

Not exactly....

I just don't care to add 6lbs of unsprung weight for aesthetics.

 

between all 4 wheels you may add 1/3 of one ounce..

 

Powdercoating will add approximately 5% to the weight of the wheel. Example: If your wheel weighs 18lbs before powder coating, it will weight about .9lbs heavier afterwards so about 18.9. This is if the stock wheel that you are powdercoating has no powdercoating on it prior (polished, painted, or clearcoat). If your wheel has been powdercoated previously then the outcome will be a wash.

 

So, 0.33oz or 112.56oz(4.02lbs)

I'm going to have to lean towards the second answer as being more reasonable. Anyone else?

BTW Each wheel weighs 20.1lbs

 

haha its going to be alot of weight.

 

wow you made this way to complicated.

it will add next to nothing. A 8 oz container could do all 4 wheels.

 

it wont be enough to fret about. pretty much next to nothing

 

I don't know what else to tell you, if you're looking for a generalized rule of thumb, 5% is it. I've seen as well as researched the matter myself..here are some of the places where I found my answers:

Also note that typically powdercoates are sprayed with a thickness of approximately 10g/sq.m or 1.5oz/sq.m so if you know the approximate size of the wheel you can use that formula. I would say that an average 18x9" wheel would have approximately 2.5 sq.m of surface area so take that and multiply it by 1.5oz and you get 3.75oz per layer of powdercoat. Typically a powdercoater will apply 2 coatings so 3.75x2 will give you approximately 7.5 oz per wheel.

 

I would argue that an 8oz container would finish one wheel...but again it depends on the thickness of the paint as well as number of layers. I suppose that you could do 4 RC car wheels with an 8oz can of paint, but on a 18x9 it would look like you spray painted it in microsoft paint.

edit* I retain my above comment if you were speaking in terms of weight, but will rescind them if you were inferring volume.

 

I just called my coater because i was curious.

He said 18" wheels would require about 4 oz per wheel.

Single color. No clear.

 

one coat or two...

 

how do u add mutiple coats to something.. u bake..? bake it again?

 

Correct. That is the case with the electro static method anyways. You may be able to do it diferently with the fluidized bed method but I've never seen it done that way so I couldn't tell you for sure. With the electrostatic method (most common for wheels and such), the powder particles are electrically charged in the gun and the wheel or object being coated is grounded. The electrically charged particles are attracted to the grounded surface like a magnet until the electric charge isn't strong enough to attach through the coating and this is why you would have to bake in order to get two coats...either that or use a higher electrical charge I suppose.
