Sigma-Aldrich Araldite(R) M

Araldite^® is an epoxy resin commonly used for embedding. It is basically free from polymerization damage and the plastic does not sublime in the microscope, hence providing continual support and preservation of fine detail.[1] It is composed of araldite M or CY 212, dodecenyl succinic anhydride, dibutyl phthalate and 2,4,6-tridimethylamine methyl phenol.[2]

Araldite^® M was used with propylene oxide in a ratio of 1:1 in the preparation of ultra-thin sections of rat liver to examine the hepatotoxicity induced by anti-oxidant food additive like butylated hydroxytoluene using an electron microscope.[3]
