Epoxy Resin Pigment - 18 Colour Liquid Epoxy UV Resin Dye Transparent Colourant for UV Resin Colouring, Resin Art Jewelry Making - Concentrated UV Resin Colourant for Paint, Crafts - 0.35 oz/10ml Each

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.

I've had chance to have a good play around with these dyes and you'll see some of my in progress tests in my photos. I'm very new to playing with resin and we are using it for the children to make mummy a present for xmas. This set is much easier on the pocket than alcohol dyes (which is what you'll see a lot of people on YT videos using) and they do behave slightly differently but keep this in mind and you might agree the cost saving makes them much better value. I found that these dyes worked best when they were thoroughly mixed into the resin, without mixing they just sit on the surface (where alcohol based might evaporate and cure). This doesn't mean that you can't use them to create droplet patterns in your casts it just means that you need to take the time to do it properly and mix it with a small amount of resin, and then use this mix for your droplets. This seems to work fine. I found that a little of the pigments goes a long way. If you want to make the piece more opaque start by building up a white based mix first, and then adding the feature colour droplets of dye one the white is mixed in. It uses a bit more dye, but gives a nice deep and opaque colour.The range of colours is quite impressive, with various tones within the main colour groups. The labels did need pressing back into place at the edges but they were still attached to the bottles quite well.

Spot on product. Good value, loads of colours and they go a long way!

Most of the colours in these are very potent, they also came with some additional nozzles for the bottles which was handy.

I used these with Gedeo resin, very lush tint which you can make more vibrant with more drops. It's tinted so dont expect block colour. The colours are crystal clear and really rich, I only had a problem with Rose colour as it somehow reacted with the resin and the colour disappeared. They'll last for ages since I only need a couple drops so very good value.

it is good resin colours but it is hard to get out of the bottle and doesn't blend properly I'd give it a 3.5 out of 5

Really easy to use. Great as a starter. Works well with UV resin but only if you allow enough transparency for light to get through it. Great colour and value for money

Great product for messing around with resin. I use craft resin and this works well for getting good pigmentation of colour. Nice vibrant colours that you can make translucent or opaque. Worth the money but these are not alcohol inks so might not work for some designs.
