I assume that like Water and Ice are still H2O.?.?. This is an interested concept and definately worth more research. I currently use Devcon 2 part Epoxy. Both the Epoxy Resin, and the Hardener bottles contain the warning "Potential Skin Sensitizer". Usually, when I research Allergic Contact Dermatitis/Eczema, I search those words specifically. I'm then taken to Medical Specialty sites that provide information. Here are a couple of sites that I refer to on my own site. http://www.eczema-ltd.com/contact.php http://www.eczemaguide.com/eczema_basics/eczema_like/contact_dermatitis.html http://www.mayoclinic.com/health/dermatitis-eczema/DS00339 http://en.wikipedia.org/wiki/Dermatitis I never considered the possibility that the properties of the resin and/or the hardener, that cause allergic reactions, could change once cured.

I couldn't find anything about reactions to <i>properly cured</i> epoxy. One suggestion: After hardening, wipe the surface of the epoxy with acetone. I use a Q-tip. This will remove traces of unhardened resin or excess hardener from the surface without significantly (noticeably) affecting the polymerized mass. Back in my radiation research days, I used a 5:1 epoxy in the lab. We'd measure out five parts of resin, and then one part of hardener on a lab scale. We'd then mix well, pour, and put on a hot plate for 10 minutes to set it. When I bond to titanium, I scratch the titanium surface that will be hidden with a needle file or a small burr on a flex shaft (Dremel equivalent) just before gluing.
