System Three Epoxy Pigment Concentrates, 2 Oz Bottle, Black

I make very small items with epoxy resin and use this for an opaque color and it works perfectly. I add VERY LITTLE to my pours as I work with 40-80g. I have bought white, red, and black of this brand and each has been exactly what I needed. Other opaque pigments I've used have not stood up to this as they require too much to be added to give it an opaque look which disrupts my resin ratio where this takes like a pin drop for the size of pours I do.

as advertised. good quality.

I bought this to use for pouring resin art, and it’s excellent.It’s a floating-white in resin, unique because white pigments are always heavier and tend to sink. So brushing color over this white creates beautiful cells.No joke, a very small amount goes a very long way. The color and opacity are great.I do not follow the instructions on the bottle when mixing, I add it after I’ve mixed my resin-just like all of my other colors- and I’ve never had an issue.

I used this with West Systems 205-207 epoxy and I'm pretty surprised just how little you need. For small batches I just dipped the mixing stick in it, let it drip off until it was just barely coated, and that was enough for completely opaque black. It dries just as hard and has a really good gloss. I haven't experienced any issues other people have mentioned like it affecting pot life or drying time, or the ability to remove bubbles via heat gun.

I purchased the 4 ounce white paste. A little does go a long way!! I am a resin artist and I use Artresin and MasterCast. System Three paste is highly compatible with both types of resin. It has not affected the pot time or the curing process!! I generally use 3 gallons of resin a month and I pretty much use white in all my work. Because so little is needed to color the resin, I expect 4 ounces will probably last over a year. I highly recommend! !!!!

I didn't even end up using the pigment. Instead I ground up some scrap pieces of granite with a hammer. The picture is of about 1 tablespoon of the epoxy and hardener (2 total) and a DROP of pigment. I wasn't confident in my ability to drop any smaller amount. If I wasn't repairing a crack with some chips it may have been fine. I gave it 5 stars because it definitely does its job of coloring the epoxy!

Be very careful how much you add if you don't want ink black, I've gone so far with an epoxy sample I wanted to be more of a smoke black to take a toothpick and get a little dye on it to add. You can always add more, can't take it back out...

Awesome... is all I can say. You only need a tiny bit to colour a lot of epoxy. Does look slightly translucent while mixing but I used it to fill voids in a hardwood floor and it turned out fantastic. Made the holes look like knots.
