What opaque pigments have you used to color epoxy to facillitate making your own surface coats?
Jon
epoxy pigments…
Which basicly are powdered pigments, milled into a small amount of epoxy resin, to make a workable paste, instead of the messy powders.
If you need the surface to be black you can just add graphite powder…otherwise follow herman’s advice.
thanks much!

Can we use those epoxy pigments to create a colored carbon laminate?
Has anyone tried before? Is there any photos around?
…
I just made a mold with Adtech surface coat, which is white. I find the white to be difficult to see any imperfections. A black surface coat would be much nicer I think. Can you give me a guideline for how much graphite powder to add to the surface coat. I could do it visually by how the surface coat looks, but I don’t want to over do it.
Thanks
Hi. Are you sure that white is worse to see any imperfections? I think that white is best color to can perceive curves and imperfections. Black color would be worse in my opinion.
One question, Could make an infusion with pigments?
Greetings
I also prefer black. The only time that I use white is when I have to use a black IMC in the mold.
Just add the graphite powder until it black enough for you. I really doesn’t take very much. Since your surface coat is white you won’t be able to get it really black…more like grey.
BTW, the adtech epoxy based surface coats don’t polish very well. This isn’t a problem if you can pull a perfect mold off a perfect plug.
you can’t colour the fibres, but the resin. The more colour, the less you will see the fabric. you can spray paint a light coat of colour over it, giving it a look like the carbon is coloured.
That was my question. I know you can’t colour the fibres.
I remember seeing a photo of a Carbon fibre part painted in red, but you could still see the twill of the carbon fibre beneath .
It looked like instead of using a clear coat, they used a very light red “transparent” coat.
thats possible, gives a nice effect, but I guess it takes some finding out how to achieve the best results.
I found this video from hp-textiles. In the final shots you can see that translucent look i was talking about.
It looks good on close up, although i doesn’t look very nice at the distance, or is it just the video?

It is patchy, probably due to differences in Vf. The resin is dyed translucent red. You need a translucent pigment for that. Not the opaque ones.
