(NMA, EPON hardener MNA, Methylnorbornene-2,3-dicarboxylic anhydride, Nadic methyl anhydride)
C₁₀H₁₀O₃ • M_r 178.19 • CAS [25134-21-8]

Methylnadic anhydride (MNA) is a hardener component for polyester and epoxy resins, for example Glycid ether 100 (formerly EPON 812) embedding for electron microscopy.
Glycid ether cured with MNA yields very hard blocks. By combining different proportions of the hardeners dodecenyl succinic acid anhydride (DDSA) and methylnadic anhydride (MNA) with glycid ether will allow the preparation of blocks with a hardness from soft to hard (1,2).
