MMA vs epon (was Immuno on JB 4 Resin)

From:"Morken, Tim"

I'm not sure what you mean by "epoxy-like resins" but, to clarify, Epon
(trade name) is an epoxy resin while MMA (and GMA) is an acrylic resin. They
have very different properties in terms of cross-linking, porosity,
strength, hardness, etc. These differences account for the reason that
people use methacrylates for light microscopy and epoxy resins for electron
microscopy. There are acrylics suitable for EM as well, however.

Hi All,

I just wanted to mention that JB-4 resin is a glycol methacrylate and
not a methyl methacrylate. Some of the epon-like resins are methyl
methacrylate and might work better for you.
