Powder Coat Resources

I wanted to start a thread on what everyone is buying for powder to powder coat bullets.
Not necessarily about how to, or what is Powder coating, that you can jump to this post to read the link to get a background on it
https://www.mdshooters.com/showpost....6&postcount=16

I"m more interested in the powders themselves, where did you get it, what color etc. Why because I"ve found that not all powder coat powders are equal. Some work out better than others and some methods of coating work for certain powders better than a generic swish and dump. Colors can matter cause So far, I have seen different colors from the same vendor come out good or bad.

Please post what powders you are buying and how they work for you and any tricks you need to employ to get them to coat/cook well.

If you can put a link to where you buy it from and what colors/formulas you have had success with.

I'll start out with what JohnFromMD recommended to me earlier this year.

www.powderbuythepound.com

Search for colors by the SKU

So far , these turn out really good

Sky Blue : SK5591
Yellow Green : SK81512
Raspberry Red : SKU210431

I"ve had NOTHING but bad performance out of Harbor Freight powder using the easy method used for powderbuythepound.

This one coats well but is somewhat translucent
Candy Rose Gold SK32221

I'm able to swirl these powders in a /5\ rubbermade container and the bullets basically soak up and coat really well. I will slowly add powder and swirl till they are completely coated with little powder left on the bottom. With this powder, if I put in too much, I need to shake excess powder off before coating.





Note: gray below is Eastwood



Rose Gold

Powder Coat Resources

Eastwood Hotcoat

Available on Amazon.
I've tried so far

Periwinkle Gray
https://www.amazon.com/gp/product/B07RLTLGPM

Gold
https://www.amazon.com/gp/product/B001EDUFCA

Although easy to get on Amazon, you get half the powder vs. Powderbuythepound. You do get a plastic container with it though. For this powder, you need to put in more than what will coat the bullet and you have to swirl more than powderbuythepound.
The gray turns out good for me but the gold did not coat very well and left gaps uncoated in the lube grooves

Gray for my 45-70



Gold and the gaps in the Grooves (top half of the bullet group) and clumping
Needs more swirling

Powder Coat Resources

Prismatic Powders

Also available on Amazon

Bronze Chrome
https://www.amazon.com/gp/product/B086XLFY59

Good price / lb , no container option like Powderbuythepound.

This coated well but seemed "clumpy" compared to powderbuythepound


Here is the Prismatic (left) next to powderbuythepound



Edit: new batch with the Prismatic Bronze gold

Oven is a Hamilton Beach with convection. I run it with convection on 400F for 20 mins



I place them on a copper sheet or sometimes directly on top of hardware cloth.

Powder coating functions the same as bullet lube for cast bullets. Fouling is kept at a minimum, and at worst, the fouling is a mixed residue of the coating, trace lead, and powder residue that is easily scrubbed off with solvent, and a bore brush or 100 percent copper mesh.

Personally, I would rather have powder coating fouling than copper fouling. Eliminates the need for intensive copper solvents.

Not sure how to address the second question, but the powder coating is baked and cured on to what it is applied on, making it hard to take off. I would guess sandblasting the stuff off, but I never had to remove powder coating on surfaces.

Best I've done to "remove" powder coating is tossing defected projos back in the melt pot, haha. Had some stick on a toaster pan once and even trying to burn and chisel it off didn't work...

Powder coating is more like an epoxy coating, than a conventional type of paint.

I can relate to this thread. Eastwood lime green shakes and bakes easy. Baked it on 350-400 and coating comes out even. Great powder for volume powder coating casts.

If you're ever at the agc pistol steel lanes, you'll see limegreen pancaked flakes embedded on the railroad tie. Public proof that they survive the hammer test. Overall quite happy with this powder.
