[Service] Keycoat Custom Powder Coating Service

Keycoat is a powder coating service that is focused on bringing your keyboards to life with premium finishes while accounting for the design and tolerances. Working very close with the shop, we have tuned the application of powder coating to keyboards.

Disclaimer: Keycoat can not guarantee that the board will fit the same way it did before powder coating. This is because powder coat is thicker than anodization and that thickness varies depending on the material the powder is made of. However, the shop has figured out ways to combat this and we have seen it with the results

What is powder coat?

Powder coat is a free-flowing, dry powder that can be applied to metals, such as aluminum, brass, copper, steel, or silver. Powder coat is uniquely applied to the metal electrostatically after being heated in an oven. Preparation for powder coat involves sandblasting previous anodization or surface finishes, preheating the metal, then spraying the powder.

The advantages of powder coat includes a reduction in the amount of volatile organic compounds released into the environment, a wide variety of specialty effects and colors not achievable in other finishes, and a durable and tough exterior finish that could possibly reduce or hide previous blemishes, scratches, or small nicks/dings.

I’ve had two boards powder coated with success but if the board has tight tolerances you might have to sand down some parts. It’s a nice way to change up the colours and get something truly custom!


Awesome service! I’ll definitely be filling out a form soon to try this out

Appreciate it Huey!

It’s a really cool service for custom boards! That’s an amazing number of color options available. I would like to see what people come up with for matching existing keycap sets.

I think the price is okay for the dream board setup, but I’ll have to see how the colors look before I take the leap. I would be putting $125 into a $150 tray mounted case. I’ll have to sleep on that one for a while.

Agree 100%. I wish I could lower the price even more. If I could I would. Maybe in the future if things start picking up.

I think this is a good service for folks in the States! I’m hoping someone in Canada will be able to open this up, as this would be really expensive for us.

Update: If you can not find a color you like on prismatic powders and you find a color elsewhere, let me know and I can ask the shop if they can accommodate that powder.

I’m in SD and will def give this a try!

Curious, how do y’all handle complex geometries like USB port holes without getting excess powder build up? I know that could be a possible worry for some cases. Would there simply be a less consistent coating in those areas? Just wondering.

For any holes, they get plugged with silicone plugs similar to these:

Here is an example of the board being plugged:

Sorry I should have been more clear. I mean holes and tight areas for the USB port and possible reset holes. I know @norbauer said some powder coaters have issues with this in tight areas.

I forwarded the image to the shop and they said that they have silicone plugs that will fit those areas to cover them.

So that interior area would be completely non coated?

Compiled a small list of past work from the shop.

The boards I had coated are pretty even but they do have trouble around port holes like that. Mine are covered enough that you can’t see the finish underneath but you can definitely tell it’s a lot thinner. The overspray seems to do a good enough job I guess.

Not trying to dissuade people from powder coating because I think it’s a great product and I plan on doing some cases myself (plus, just look at what Norbauer puts out there) but for anything with tight tolerances, Cerakote is a good option because it tends to be much thinner.

The interior area will be coated evenly however the actual hole will be plugged. Sorry about the confusion.

While cerakote is thin and about the same thickness as anodizing, I have talked to the shop about tolerances and they have agreed to make the coat as thin as possible without losing the characteristics of the powder. However, like you said, for boards with tight tolerances there is always the risk of powder coat being too thick even at the thin coat the shop will do.

Yes, you really should have a case that was intentionally designed with powder coat tolerances in mind from the beginning, especially if you plan on using textured coats. That or at least have a thoughtful look over all the mating surfaces on your parts and see if adding some bulk in those areas might cause problems. For many housings, I think it wouldn’t be an issue at all, but it’s something to bear in mind because there are definitely cases where it can cause issues. I have experienced it myself in early prototypes where I had to tweak some clearances to make sure the textured powder coats would fit without being abraded by a mating surface, or even preventing a clearance fit.

By the way, this is really good pricing for a one-off powder coat service. Even small mom-and-pop shops here in California tend to charge a lot more. And the current industrial coater I’m working with (which admittedly has fairly serious equipment and capabilities so it’s not directly comparable), has a color lot minimum of around $1000.
