[Nhcoll-l] Long term storage of slides mounted with "DevCon 2 Ton" epoxy?

[Shoobs, Nate]

Hey all,
A researcher (with permission) prepared thin-sections of about a hundred freshwater bivalve shells from our collection. The established protocol for making this type of thin sections is to use a common epoxy resin: “DevCon 2 Ton epoxy<https://itwperformancepolymers.com/wp-content/uploads/2-Ton-Epoxy-TDS-v4.pdf>” to mount the thin sections on glass slides.

Does anyone have any experience with slides (or anything else) mounted using this epoxy long-term?  The main things I’m concerned with are yellowing and shrinking.

The researcher will likely be making many more slides with this method, but is open to using another epoxy if I suggest one, so if there are more stable alternatives, I’d be happy to hear about them.

-Nate
