Solvent-free, modified bisphenol A epoxy resin. Epoxy equivalent weight 232-250. Yields 3-dimensional crosslinking blocks.Non-toxic substitute for ARALDITE® CY 212, which contained dibutyl phthalate. Renlam® M-1 has identical properties as ARALDITE® CY 212 and can therefore be used in all electron microscopy protocols in exactly the same way as ARALDITE® CY 212.
