So after 3 cans of PR resin I still haven't figured this out.
I want to make a two color swirled blank. I've begun waiting longer that I did at first to do the mixing...boy once that catalysts kicks in you don't have much time...but it takes a while for it to reach that point.
So I mix = parts in separate containers of resin & black powder coating in one and resin & blue nail polish in the other.

They look great siting in the mold and I've even swirled with a tooth pick...Every one the black either sinks to the bottom or the blue totally disappears and this is a light blue not any where near dark..........
Please let me know what I should do different
Thanks

I am far from close to knowing much about casting, but you may be pouring the black in first then the blue? I'm not sure if nail polish is usable in PR so that may be an issue. Try pouring both at the same time then get your choice of swirly stick out and have a swirl at it!
 
I am also not an expert, but I do know different colors set at different rates. Especially the black that we have made sets REALLY FAST (couple minutes)

Red is REALLY SLOW (can be days).

So, make a single color blank first to determine how long it takes for each one, individually to set. Then, when you make the mix, you will have a "fighting chance" of getting it right.
 
I've found that paints take longer to setup than pr. The fingernail polish is probably causing some of your headache. Are you using the same amount of mekp for both colors as well?
 
The fingernail polish and the powdercoat paint are your main problems. I'm betting the reason why the black is settling is bc it's so much heavier than the blue.

Personally, I'd invest in some mica powders from coastalscents.com They have solid black and several shades of blue.
 
Thanks all
I have tried mixing together and even a little of one then the other - like layers in a cake.
I'm going to try the mica powders and......................wait longer
Thanks again
 
Definitely go with what Brooks said. Using mica or Pearl Ex will help even the weight differences, plus the pigments will blend well together if you want to make new colors.
