VEctomer®
Vinyl Ether
Composition
VE 4010 - 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
Structure:
VE 4010 is a difunctional aromatic
monomer that enhances the performance of radiation cured coatings, inks
and adhesives. VE4010 improves adhesion to PVC, plastic and metal
substrates. VE4010 boosts cure speed in cationic epoxy cured
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 - 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.
·
VE4010 may crystallize at low
temperatures below 10 C. May be heated to 45 C to facilitate mixing
and handling if this occurs.
·
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
