18 Color Epoxy UV Resin Pigment - Liquid Epoxy Resin Dye Transparent Colorant for UV Resin Coloring, DIY Resin Art Jewelry Making - Concentrated UV Resin Colorant for Paint, Crafts - 0.35 oz/10ml Eac

Work great and easy to use

Bought this specifically as states they are useable for UV resin if mixed in before curing and small amount used. Can confirm I have been able to successfully use these without damaging moulds when working with UV resin. Good quality colour from very small amount of dye used. Would recommend and buy again. Unable to comment on how well the colour lasts as not made any pieces for significant time yet.

Disclosure: I bought this product at full price like a normal person.3D printer UV resin is expensive enough already, and paying a ton of money for colors I might use a few times feels wasteful.I could say a lot about this product, but all you really need to know is 1) it's well packaged, 2) it's easy to mix thoroughly, and 3) it totally works.The pink in the pictures is from the "peach" color, which was very obviously a deep pink looking at the bottle. All the colors are named after fruits or flowers, so it'll be nice and easy to keep track of what I used in my notebook.I put 10 drops into 30mL of white resin (the mixing cup picture is after 5 drops), and the results speak for themselves. A drop is officially measured as 0.05mL, so there'll be about 200 drops in a bottle. Given all the different colors included, this set will make a LOT of pretty prints.I'm neeeeever buying pre-colored resin!!PS: I also bought amber-tinted glass bottles to store my mixed colors in (https://amzn.to/2NZE6gU)

Awesome, colours are great and very strong, needing only a small amount to add colour to resin.

These are extremely pretty, just don't use too much foe UV resin, we found that they didn't cure properly when we used a lot of color concentrated in one area.
