System Three 3201A24 Black Paste Pigment Coating, 1 gal Can

I got this after seeing it being used on youtube, its a great product and you need such a little amount I will have this little bottle for a long time. I used epoxy to fill in the crack and wanted to give it a bit of color.

This is my experience with this product, yours may be different. I use this with Epoxy-it 80 brand Clear Epoxy Resin for Bar Tops, Encapsulating, or Casting (1 Gallon) at 75 degrees F. Without this pigment the epoxy goes on smooth, bubbles pop easily and you have a long working time. With this pigment, the epoxy develops some large bubbles that will not pop not matter how much heat you apply. The only option is to sand them out and top off the project with a clear coat. The work time for the epoxy is reduced to about fifteen minutes then the stuff starts to gum up. Self leveling is a thing of the past.On the plus side this is the "strongest" pigment I have seen. I mix batches in 12 to 16 oz pours. .As the other reviewer said an amount about the size of a pea is almost to much. It mixes into the resin easily.

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.

Ok for the purpose. Very dark, very glossy. Use as little as possible. Too much will increase the dry time significantly and will make the bond very elastic and soft.

Did what it said it should do. I added it to JB Weld and repaired the edges of my ski topsheets. They are black, so the pigment changed the grey JB Weld black to match. No problem with the setup time for the epoxy with this pigment in it.

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! !!!!

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.

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!
