Properties of PI-907

PI-907 is a yellow crystalline powder with a molecular weight of 295.4 g/mol. It has a melting point range of 60-64°C and a boiling point of 476.5°C at 760 mmHg. This photoinitiator is insoluble in water but soluble in most organic solvents, such as acetone, ethyl acetate, and toluene. It has a strong absorption in the ultraviolet (UV) region, with a maximum absorption wavelength at 288 nm.

Applications of PI-907

PI-907 is widely used as a photoinitiator in various industrial applications, such as UV-curable coatings, inks, adhesives, and dental materials. It initiates the polymerization process when exposed to UV light, resulting in the crosslinking of the polymer chains and the formation of a solid coating or adhesive. PI-907 is known for its high reactivity and efficiency in initiating polymerization, making it a popular choice for many UV-curable systems.

In UV-curable coatings, PI-907 is used as a photoinitiator for acrylic, polyester, and epoxy resins. It provides fast curing and high crosslinking density, resulting in a tough and durable coating with excellent adhesion and chemical resistance. PI-907 is also used in UV-curable inks for printing on various substrates, such as paper, plastic, and metal. It enables fast curing and high printing quality, with good adhesion and scratch resistance.

In dental materials, PI-907 is used as a photoinitiator for dental composites and adhesives. It provides fast curing and high conversion of monomers to polymers, resulting in strong and durable restorations. PI-907 is also used in other applications, such as 3D printing, electronics, and optical fibers.

Manufacturing of PI-907

PI-907 is manufactured by INNO Specialty Chemicals using a multistep synthesis process. The process starts with the reaction of 4-methylthiophenol with ethyl acetoacetate in the presence of sodium ethoxide, resulting in the formation of 2-methyl-4-(methylthio)phenyl-3-oxobutyrate. This intermediate is then reacted with morpholine and acetic anhydride in the presence of sulfuric acid, resulting in the formation of PI-907.

The manufacturing process of PI-907 involves several critical steps, such as reaction conditions, purification, and quality control. INNO Specialty Chemicals has a state-of-the-art manufacturing facility equipped with advanced equipment and experienced personnel to ensure the quality and consistency of its products.
