Composition
VE 4060 - vinyl ether terminated aliphatic ester monomer: HBVE adipate;
bis-(4-vinyl oxy butyl) adipate
Molecular weight = 342 (g/mole)
Formula: C18H30O6
CAS # 135876-36-7
Description
VE 4060 is a difunctional aliphatic diluent monomer. It is a low viscosity clear liquid
that enhances coatings, inks, adhesives and other radiation curable formulations with an
outstanding balance of physical and functional performance.
Product/Application Benefits
- Fast cure speed
- Low initiation energy
- High gloss
- Good flexibility
- Low viscosity
- Low odor
- High solvency for vinyl ether oligomers and cationic initiators

Viscosity / Temperature / Composition
The graphs below show viscosity as a function of temperature for VE
4060 . VE 4060 is compatible with
the full range of VEctomerä oligomers and other vinyl ether
diluent monomers useful for carbocationic polymerization.
Photoinitiators
Photoinitiators for Cationic Cure - 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 sensitve applications.
2) Irganox 1076 (1% w/w) can be used to reduce discoloration on heating.
Gentle heating often improves photoinitiator solubility.
Recommended Curing Conditions
Formulations containing VE 4060 along with VEctomerä
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.
