Properties of PI-907

PI-907 is a white to off-white powder with a molecular weight of 357.5 g/mol. Its chemical formula is C17H22NO2S, and its CAS number is 71868-10-5. PI-907 is soluble in many organic solvents, including acetone, ethyl acetate, and toluene, but insoluble in water. It has a melting point of 74-76°C and a boiling point of 392.6°C at 760 mmHg.

PI-907 belongs to the class of alpha-diketones and contains a morpholine group and a methylthiophenyl group, which make it highly efficient in absorbing UV light and initiating radical reactions. It has a high photoinitiating efficiency, low toxicity, and good compatibility with various resins and monomers, making it an ideal choice for many industrial applications.

Applications of PI-907

PI-907 is a versatile photoinitiator that finds applications in many industrial processes that use UV or visible light. Some of its main applications are:

1. Printing: PI-907 is widely used in printing inks and varnishes to cure the ink film and create a durable, glossy finish. It is compatible with various printing techniques, including offset, flexography, and screen printing.

2. Coatings: PI-907 is used as a photoinitiator in coatings to create a hard, scratch-resistant surface. It is suitable for both solvent-based and water-based coatings and can be used in various substrates, including metal, plastics, and wood.

3. Adhesives: PI-907 is used in adhesives to create an instant bond between two substrates. It is particularly useful in applications where fast curing is required, such as in the manufacture of electronic components and medical devices.

4. Electronics: PI-907 is used in the manufacture of electronic components, such as printed circuit boards (PCBs), to create a high-quality, durable surface. It is also used in the production of optical fibers and other photonic devices.
