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 5015 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.
