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

It's good. It wasn't strong enough to paint white polyurethane black, but I didn't expect it to. It gives a nice graphite color to the two-part white polyurethane

I used this to add a deep pigment to pool putty to repair cracked tiles. It mixed well and is holding up to daily UV and pool chemicals.

Very intense color. A little goes a long way.

The green is blue. Not a little blue. It is royal blue. Nice dye otherwise.

These are the most concentrated pigments I have ever used. If you use a very small amount it is translucent if you use a small amount more you can get almost black. Be very carful, start with lest than a drop. I put a drop on the sterling stick then wipe off most of it. You can get light translucent color to dark by changing the amount. My only issue is the the bottle leaked. The trick is the bottle has a paper seal then a foam ring seal. Poke a hole in the paper but leave the foam ring. This give a better seal.

This stuff is great. It's not like those bad resin dyes that hardly change the resin's color. I used 1 small drop in 100ml and it made it inky black like oil. Amazing. I'm going to buy more colors from them.

I make dice, and purple alcohol inks tend to turn a burnt color as the resin cures, so I needed an alternative. This stuff doesn't affect the curing, but is -very- tinted. the amount needed to make a clear purple is 1/10th the amount you think it is, which is awesome because it means it will last a long time! Will be coming back for more when I run out :)

I’ve worked with a lot of different dyes for resin projects, but this one stands out immediately. The biggest advantage is its incredible concentration, (don't let the size fool you) literally a single drop goes a very long way! Because of this potency, you can achieve anything from subtle transparent hues to very rich tones. The pigment disperses smoothly through the epoxy without clumping, streaking, or leaving behind any grainy texture. If you want strong, reliable color without waste at a great price, this is the product to reach for.

Worked exactly as needed and as described.

Used for lacing in resin to give surf effect, works well.

Excellent

Like this product use it for my carbon fiber fabrication.

It’s a game changer and I’m so glad I bought this. It really brings some of my resin art to life!
