Bis(.eta.5-2,4-cyclopentadien-1-yl)bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]-titanium
PowerCure™ 784 is a very reactive, cationic type solid photoinitiator. It is very sensitive to light with photobleaching effect, and it can be used in light-solidification system initiated by visible light. It is mainly used in high-tech and high value-added fields, such as argon laser scanning curing, holographic laser imagery.

PowerCure™ 784 may be used for UV and/or visible light curable formulations based on chemically unsaturated systems after adequate testing - such as those based on a prepolymer - e.g. acrylates in combination with mono and multifunctional monomers as reactive thinners.
The best curing performance of PowerCure™784 can only be achieved in the absence of oxygen.
PowerCure™ 784 can be used in photopolymers, e.g. resists, printing plates and other information storage devices such as optical layers, holograms, laser direct imaging, stereolithography due to its unique absorbance properties together with its outstanding reactivity. 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.
In addition, PowerCure™ 784 can also be used in coatings, inks or adhesives.
The amount of PowerCure™ 784 required for optimum performance should be determined in trials covering a concentration range. Recommended dosage is 0.1-0.5% w/w.
