ERL 4221 (was 4206)
ERL 4221 Epoxy monomer
Vinyl cyclohexene dioxide
Due to the supply shortage of ERL-4206, ERL-4221 has now been specially formulated to replace it. ERL-4221 may now be used as one of the main components of the low viscosity Spurr's embedding resin kit
ERL-4221 is a Cycloaliphatic Epoxide Resin.
