Application
Photoinitiator 784 is an extremely reactive, orange colored solid photoinitiator
for radical olymerisation of unsaturated resins upon exposure to visible light
(daylight) or UV light. It has a wide absorption in UV spectrum with the typical
absorptions at 390 & 460 nm and the absorption extends to 500 nm. It is especially
suited for the curing of photopolymers for imaging or information storage
applications. It may be used in UV curable formulations for clear and for
pigmented coatings on wood, metal, plastic, paper and optical fibers as well as
for printing inks.


Its unique absorbance properties together with its outstanding reactivity make it
especially suited for use in photopolymers, e.g. resists, printing plates and
other information storage devices such as optical layers, holograms, laser direct
imaging, stereolithography. Curing can be performed either using UV light, visible
light (blue-green part of the spectrum) or even light from suitable laser devices,
e.g. Ar-Laser (488nm) or FD-Nd/YAG-Laser (532nm). Best performance is obtained if
oxygen is excluded from the resin system during curing.
