| introduction | photoinitiator 784 is a very active orange solid photoinitiator with good photoactivity, thermal stability and low toxicity. as a reactive diluent, it is mainly used for UV and visible light curing of unsaturated prepolymers together with single or multi-functional vinyl monomers and oligomers. Especially suitable for imaging or information storage photosensitive resin curing in high-tech content and high value-added fields, information storage equipment, such as photosensitive layer, holography, laser direct imaging, three-dimensional flat printing, etc. It can initiate the polymerization reaction of unsaturated resin under the action of visible light or ultraviolet light. Curing can be carried out under ultraviolet light, visible light or even suitable laser irradiation, such as Ar-laser (488nm) and FD-Nd/YAG-laser (532nm). The curing performance obtained by isolating oxygen during the curing process. |
| advantages | 1. it has high photosensitivity and high sensitivity from ultraviolet to visible light 2. it can effectively cure thick films and can cure coatings with a thickness of more than 70 μm 3. it is suitable for dark light curing coatings 4. safety, environmental protection and hygiene |
| features | its photoinitiation process is neither a cracking type nor a hydrogen capture type. Due to the special photoinitiation mechanism of 784, it is very suitable for thick coatings and dark curing systems. It can cure coatings with a thickness of more than 70um and black, red and high pigment coatings; plus 784 ultra-wide ultraviolet and visible light absorption The spectrum band can make full use of the light source, so it has high photosensitive sensitivity and photoinitiation activity. In addition, the photolysis fragments are complexed by acrylate and do not migrate to the surface, so they are safe and environmentally friendly. In addition, 784 have good thermal stability. table 1 shows the specifications and physical characteristics of photoinitiator 784 |
