Coloring epoxy

[Guy Thomas]

Does anyone know if the carbon powder from spent copier toner cartridges will work o.k. for coloring epoxy black?

I don't know about carbon powder, but a drop or 2 of leather dye will do it,or a little hobby paint.

Should work just fine. I use the dry pigment from K+G, but the toner should work. Just remember that a powder will make the epoxy thicker.

Black Waterproof india ink makes it nice and black, you can also use model paint and use just a little. I use the ink for black and it tends to make the epoxy harden a little harder, some additives make it rubbery or take a long time to cure, just play around with some and some scrap, remember there is such a thing as too much color in your epoxy, it can make a mess!!!just a little goes a long way..

You can use rit fabric dye, which you can get at almost any grocery store or walmart. I have used the powdered kind in several different colors, but I have been told the liquid works also.

Try it.....most powder toners used in copiers and computer printers are primarily plastic. It bonds to paper by melting after being heated.

Or, if you want to play it safe and not worry about whether the additive will dilute or affect the chemical reaction and bonding properties of the epoxy, you can get black industrial strength epoxy such as Conap which Sheffield carries. Comes in black, white, clear, and translucent.

Be careful with toner it is a carcinogen ( causes cancer )

I've been using copier toner to dye epoxy for many years. It works just fine.

I was going to say the same thing about copier toner...It is considered a hazardous material...contains Selenium ? Anyway its one of those things that is probably OK unless you huff a handfull of it.)or absorb small traces amounts of it frequently for a long period of time.) I use black iron oxide to tint epoxy. It comes a very fine powder from the ceramics suppliers, very cheap, and a little goes a long way.

The last time I talked to Dr. Hrisoulas he said that the boating industry makes high strength epoxies in a full spectrum of colors, and that's what he's been using for awhile now. He said it was available at boating supply places as a repair material. I haven't tried it, since I'm really poor and just mix some sawdust from my handle material to match, but when I'm richer I intend to try it out.
