Alumilite Liquid Color Dye (Brown, 1 oz) Highly Concentrated Tint for Casting Resin, Polyester, and Urethane - Ideal for Clear, Translucent, or Opaque DIY Arts and Crafts, Beginners & Professionals

This should last me forever. A drop OR LESS will do it. I use a tooth pick to add each time until I get the color I want in my resin. No issues at all and the colors are perfect!

I was working on a star wars inspired design and tried to create epoxy panels similar to those seen in the movies on the death Star. My first attempt (in the first photo) was with white mica powder. No matter how much powder I added, it kept a translucent look, ruining the design. On recommendation I tried the alumilite dye next and as you can see the second photo, it came out fantastic. Both photos are before sanding down the extra epoxy but you can still see the results from each.

This is a beautiful shade of blue. Be careful as to how much you add; it does not take much so add a drop at a time.

It works great. Very dark, a little goes a long way. BUT, if you are coloring epoxy for woodwork, I'd use a powder instead of this, as it dyes the wood (even hardwood, like cherry) if you drop any on the surface.

Very dark blue

I used this for commercial epoxy products, 1 drop could easily affect the color of 20+lbs of epoxy. Solid color, easily diffused, and didn’t effect cure times.

Exactly what I was looking for.Works great, has good color saturation.

It was delivered solid. I needed it for my project so I let hot water from tap run on it for 30-45 secs. Some thick liquid came out and just created a mess out of my material. Doesn’t mix at all. The stirring stick I used to stir had most of the dye just stuck to it. Sending it back!
