Fallguy, do you know if you can add the dry pigment to the hardener?

Check the MSDS for both the tint and the resin.
Maybe...not sure.

The pigments I got from s3 are resin adders.

I think they are actually inert.

But they only advise adding to the resin for some reason I don't recall.

You can get powder pigments that you add to a medium, like wood flour, but you add so little as to not change the viscosity of the medium. Was wondering with all your research into epoxies you ran across using powder tint in both the resin and hardener. The blue in one and yellow in the other to get green when mixed thing.

I didn't do it Ken because it seemed like an easier thing for the manufacturer. I get epoxy in square 5 gallon jugs, or 1 gallons. To get the powder in and mixed would be really hard. You'd need some sort of mixing paddle that would insert into a 1" hole. Then you risk contamination if you ever put the hardener stirring paddle in the rein, etc.
