ERL-4221 (3,4-Epoxycyclohexanemethyl 3,4-epoxycyclohexanecarboxylate)
C14 H20 04
3,4-Epoxycyclohexylmethyl-3’,4’-epoxycyclohexane carboxylate (ECC), also known as ERL-4221 is a cycloaliphatic, diepoxy functional organic compound that is a useful building block in the production of semi-hard to hard cured epoxy resins that are suitable for use at high temperatures. It can be used as a casting resin, in reinforced plastics and solvent-free adhesive system for UV resistance and anti-radiation properties.
ERL-4221 is often used in plastic embedding kits for electron microscopy. Polysciences makes number of low viscosity embedding kits containing ERL-4221:
- 17706-1 - Ultra Low Viscosity Embedding Kit
- 01916-1 - Spurr Low Viscosity Embedding Kit
- 21961-1 - Spurr Low Viscosity Mini Kit
Specific Gravity: (20°C) ~ 1.17
