Syna Epoxy 21 (UVR6110, ERL4221)
Chemical Name: 3,4-Epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate
CAS No.: 2386-87-0
Syna-Epoxy 21 is miscible with a wide range of organic solvents, including acetone, ethanol, and benzene. It’s low viscosity and good fluidity makes it suitable for use in bulk manufacturing. The long term stability at ambient temperature is very good. It will react in the presence of acid anhydride curing agents at higher temperature. With above 200℃ martin heat resistance, the cured product is suitable for use at high temperatures between 200-250℃ for long periods.
Syna-Epoxy 21 can be used as a casting resin, in reinforced plastics and solvent-free adhesive giving outstanding performance for UV resistance and anti-radiation properties. It is a unique structure which also gives increased alkali and water resistance.
