Environmental Technology Castin'Craft Opaque Pigment - Blue (1 oz Kit) Color for Polyester Casting Resin & Clear Epoxy | Coloring Liquid Tints & Dye Art Supplies for Artists, Artisans & Hobbyists

Bright, vibrant, bold color; while using only a little bit.

I wanted to make a new workbench for my woodworking. Thought I would kick it up a notch by V-carving my business logo into the top and filling it in with colored epoxy.After carving the MDF top with my carving machine, I filled in the carved areas with 30minute epoxy tinted with this blue pigment.The color came out beautiful and contrasts nicely with the finished MDF that has a golden hue to it.There doesn't seem to be any deterioration of strength in the epoxy from using this. It actually held up to belt sanding quite well.If you're mixing a lot of epoxy with this, either try to do it in one batch (not recommended if it's a lot as was in my case) or use a measuring system to keep the color consistent across batches.You can also get some neat effects by the amount of stirring you do. For instance, if you mix the epoxy itself first and then add a drop of this. Doing only a few slow stirs will give a marble, swirly type of effect.I suppose you could mix separate batches of different colors and then pour them together to get layers or intertwined colors if you give a couple stirs too.Have fun!

I was using another blue but it kept the surface tacky. I saw that this was specifically for Polyester so I gave it a try. It is fantastic. The color can go from solid to a gradual translucent transition which is really what I was looking for. I mixed some heavy to check for tackiness and it worked great. I have already purchase more of their colors.

This pigment is perfect I mixed it with casting epoxy..The bottle is a little but you only need a very tiny amount to get color and then you can add more to make it darker.But trust me you don’t need very much at all it’s awesome

I absolutely love this pigment. I use both the transparent and the concentrate and couldn't be happier with how my resin projects turn out. I won't order from any other company for my projects.

A little goes a long.....way. Great product! This is a single drop of the pigment in the epoxy mixed up for one half of the bridge lettering at a time.

Added a bright blue to my clear epoxy. Used it to match my ski color when I was patching the top coat. Cheaper than hiring someone to do it but I have enough to last 10 lifetimes.

Used literally one drop in clear resin and had one heck of a blue. Use only small amounts of this!!! A little goes a long, long, long way!
