How do I thin out 2-part epoxy? Answered
I'm wanting to make some micarta-like material, using two-part epoxy and paper. I've done a test run, and the material was rigid after it had cured for a few days, but didn't cut like I hoped it would, because the epoxy didn't penetrate the paper. Part of the issue was that the paper was coated, but I'd also like to thin out the epoxy some so that it will soak into the paper better. I'm inspired in this endeavor by these two instructables:
The epoxy I'm using is 3M Scotch-Weld DP-190. The label says it contains epoxy resin, polymeric diamine, kaolin, and carbon black. The complete MSDS is here. This is what I'm using, because it's what I have. Got a case of these two-tube dispensers cheap at a yard sale. :-)
So, what can I use to make this more liquid? Right now the consistency is a little bit thicker than honey. It doesn't spread out when applied to paper, and doesn't soak in at all. My limited knowledge suggests that toluene, listed on the MSDS, might work, but I'm hoping for something a bit less volatile.
I'm aware that whatever I do is likely to extend the curing time, but that's not necessarily a bad thing.
