Powder coat issue

I finally got to try some Sherwin Williams powder.... I got a gray, and Kubota orange.
I did some bullets with the orange, then decided to try the gray. As I shook out the bullets into my mesh tray, there apparently was still some orange powder on it, which the gray ones picked up. These are the ones in the plastic tub.

I then did another batch with mostly gray, and added a little orange to it. I turned them a sort of brownish/bronze color. This pic is four of them with the plain gray beside them..... Different.
This powder appears to work very nicely.

As an aside.... I have found that parchment paper works much better for "no stick" than the no stick aluminum foil... I used a piece of it for two bakings so far... it turns sort of brown, but the bullets don't stick to the paper at all.... just pick 'em up.

I went back to parchment paper. I still have silicone sheets but powder sticks to them and transfers to the bullets. I keep the same color for each sheet so it does not transfer. But I don't worry about it with the paper. Like others, bake it twice and pitch

Yup copper oven liners are by far tge best I have found. Parchment is good but dosent last.

Color transfer is on you as how clean you are. Of coarse we all know its just a OCD "thing" that we even mention it.

Damp cloth picked up all the colord dust from my baskets. Moisture is not a worry because I keep the baskets on the oven. (Warm) I warm bullet before coating.

Looks good keep trying things you will find a way that works for you. We know what we like you just need find yours.

I get two to three uses out of a sheet of Reynolds parchment paper before I have to toss it. No color transfer issues as I don't have excess powder on my bullets when I place them on the sheet. The wife has been using some brown parchment paper liners in the air fryer the past several months, think I will try one of those next time I have some PC to do and see how long they last, a 100 pack is around $10 on Amazon.

I shake the heck out of my bullets in a SS colander before I dump them into the tray. Powder still sticks to the silicone mats a little. Then the next time if it is a different color that transfers to the bullets. Sometimes a little, but sometimes t can be a lot. With the paper it never does this. It is really a visual issue than anything.

has anyone tried wet powder coating. I am getting a rather rough finish to bullets shaken dry in a Triangle 5 container but putting them in a creamy mix of powder and acetone gives a really smooth even coating provided you get the consistency of the 'cream' right. I pick them out with foreceps, let them drip off the excess and stand them on their bases on baking paper. having read the 'wisdom' on this post I will experiment with temp. more than in the past, at the moment, I just put them in at 180 C for 20 mins.

I've used acetone to make "paint" but it flashes off too fast and after getting a few on the baking sheet the rest sre gumming up. I use airsoft bbs and shake, the coating is very evenly distributed which matters for precision work.

I have found that a real easy way to powder coat is to shake off excess powder with a stainless steel collender, and then simply dump the boolits onto a piece of 1/4" hardware cloth that completely covers the bottom of your ovens pan. When the cure time is reached, let the boolits stay on the hardware cloth until cool and then shake the screen over a clean empty trash can. Any boolits that stick to the screen can be easily removed by flexing or bending the screen slightly until the boolits fall off. It amazes me how the powder flows around the boolits so well because of the minimum contact with the screen. I have used the same screen for at least 50 trays and it shows no signs of deterioration. Powder actually bakes onto the screen cloth in those area that are not in contact with boolits. Therefore the same screen can be used for all colors anytime!

IIRC 160 is about 350-F
180 is more like 400-ish.
you want to make sure you have an even 400, and not oh it says 180 on the dial i'll put it there for 20 minutes.

the fluff your seeing should go to a wet stage and flow around the bullet.
then you need 20 minutes of 400 [for real 400 not dial 400] to cook the powder.
it still takes a bit to cure.
i turn the oven off and let it just sit there for a couple of minutes after the 20-22 minutes then roll everything around and dump them into a bucket of water.
take them out and dry them off in front of a fan and let them sit for at least a day before sizing.
