Product category: Epoxy resins (EP)

Syna Epoxy 21 (UVR6110, ERL4221)

Chemical Name





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.

Appearance: Colorless to pale yellowish liquid

Viscosity(cps): 350-450

EEW: 131-143

Color: 100 Max (Pt-Co)

Storage Condition: At room temperature between 5℃ and 25℃.

Syna Epoxy 07 (UVR6107, ERL4221E)

Chemical Name

3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate




Replacement for CYRACURE UVR-6107 Cycloalphatic Epoxide

Syna-Epoxy 07 Cycloaliphatic Epoxide is a low viscosity base resin.

Syna-Epoxy 07 Cycloaliphatic Epoxide resin is useful in applications requiring viscosities lower than that which can be achieved using Syna-Epoxy 21 Cycloaliphatic Epoxide.

Specific Gravity at 25 ℃: 1.167 to 1.182

Viscosity (cPs @ 25 ℃): 250-350

EEW: 130-140

Color (Pt-Co): 0 to 50

Acidity, Wt%: 0.0 to 0.1

Water. Wt%: 0.00 to 0.05
