Description
Bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]titanocene, also known as Photosensitizer Irgacure 784, is an excellent photoinitiator used in a variety of holography material systems. It belongs to titanium‐complex free radical photoinitiator. As a highly active orange solid photoinitiator, Bis[2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]titanocene has good photoactivity, thermal stability, and low toxicity. Irgacure 784 has high solubility doped in liquid methyl methacrylate (MMA) monomer, far more than the photoinitiator PQ[1-2].
Uses
BIS(2,6-DIFLUORO-3-(1-HYDROPYRROL-1-YL)PHENYL)TITANOCENE is a highly active orange solid photoinitiator with good photoactivity, thermal stability and low toxicity. As an active diluent, it is mainly used for UV and visible light curing of unsaturated prepolymers together with single or multi-functional vinyl monomers and oligomers.
Hazard
Toxic to aquatic life with long lasting effects [Hazardous to the aquatic environment, long-term hazard]; Flammable solid [Danger Flammable solids]; Suspected of damaging fertility or the unborn child [Warning Reproductive toxicity]
