VEctomer®
Vinyl Ether
VE 4010 Monomer
Composition
- Vinyl ether terminated aromatic ester monomer: HBVE isophthalate; bis-(4-vinyl
oxy butyl) isophthalate
- Molecular weight = 362.43 (g/mole)
- CAS # 130066-57-8
- Formula: C20H26O6
Description
VE 4010 is a difunctional aromatic diluent monomer. It is a low viscosity clear liquid
that enhances the performance of radiation cured coatings, inks and adhesives. VE4010 improves adhesion to PVC and metals. Cure speed is boosted in
cationically cured epoxy formulations.
Product/Application Benefits
- Fast cure speed
- Low initiation energy
- High gloss
- Good flexibility vs. hardness
- Low odor
- Low viscosity
- High solvency with vinyl ether oligomers
- Optimized for compatibility/solubility with commercially available cationic initiators

Photoinitiators
- Photoinitiators - Triarylsulfonium salts
- Union Carbide UVI-6974, UVI-6990, 3M FX512, Degussa KI-85.
- Photoinitiator level - 0.3 - 2.0% (w/w), for coatings up to 6 mil thickness.
Notes:
1) UVI-6990 gives slightly slower cure speeds than UVI-6974. However, UVI-6990 is
recommended in color sensitive applications.
2) Irganox 1076 (1% w/w) can be used to reduce discoloration on heating.
3) Gentle heating often improves photoinitiator solubility.
Recommended Curing Conditions
Formulations containing VE 4010 along with VEctomerÒ
oligomers and initiator may be UV-cured at 50 to 500 mJ/cm² (approx. 500 to 50 fpm) with
two 200 watt/inch medium pressure mercury arc lamps). Vinyl ether formulations containing
initiators may be cured with electron beam irradiation at 1 to 4 mrad.
Vinyl ethers cure by an acid-catalyzed reaction. Basic components such as amines in the
formulations should be avoided.
Curing is not inhibited by oxygen but may be inhibited by high atmospheric humidity.
Inhibition (if any) will depend on the formulation, substrate and temperature in the
curing zone.
Storage and Handling
May be heated up to 65 °C for short periods to facilitate mixing and handling.
Mixtures containing initiator should be protected from prolonged exposure to
fluorescent lights or sunlight.
Materials should be stored at room temperature, away from sunlight or UV radiation.
Please refer to MSDS for additional information regarding safe handling and environmental
precautions.
