Photoinitiator 907: A Reliable Solution for UV Curing Applications
UV curing technology has revolutionized many industries, making it possible to achieve faster and more efficient production processes. One of the critical components of UV curing systems is photoinitiators, which initiate the polymerization process by absorbing UV radiation and generating free radicals. Photoinitiator 907 is a highly effective photoinitiator widely used for UV curing applications.
Manufactured by INNO Specialty Chemicals in China, Photoinitiator 907 (also known as PI-907) is a type of alpha-ketone-based photoinitiator that exhibits excellent performance in various applications. It is a colorless to pale yellow liquid with a molecular weight of 357.47 g/mol and a boiling point of 125°C. The product is soluble in many organic solvents and has low volatility, making it easy to handle and incorporate into different formulations.
One of the main advantages of Photoinitiator 907 is its high reactivity and efficiency in initiating polymerization. It has a broad absorption spectrum ranging from 250 to 420 nm, which allows it to absorb UV radiation from various sources, including mercury vapor lamps, LED lamps, and arc lamps. Upon absorption of UV radiation, PI-907 undergoes a photochemical reaction and generates reactive radicals, which initiate the polymerization process. Due to its high efficiency, a small amount of PI-907 is sufficient to initiate polymerization, reducing the overall cost of UV curing processes.
Another significant advantage of Photoinitiator 907 is its compatibility with various monomers and oligomers. It can be used in combination with acrylates, methacrylates, vinyl ethers, and other unsaturated compounds to form highly cross-linked polymers with excellent physical and chemical properties. In addition, PI-907 exhibits good thermal stability, allowing it to withstand high temperatures during curing without degradation.
PI-907 finds extensive use in various UV curing applications, including coatings, inks, adhesives, and composites. In coatings, it provides excellent surface curing and improves the scratch resistance, hardness, and chemical resistance of the cured films. In inks, PI-907 enables fast curing and improves the adhesion and gloss of the printed surfaces. In adhesives, it enhances the bonding strength and durability of the cured joints. In composites, PI-907 improves the mechanical properties and provides a high degree of resistance to weathering and yellowing.
In conclusion, Photoinitiator 907 is a highly efficient and versatile photoinitiator widely used in UV curing applications. Manufactured by INNO Specialty Chemicals in China, PI-907 offers excellent performance in various formulations, exhibits high reactivity and compatibility with various monomers, and provides excellent thermal stability. Its broad absorption spectrum and low volatility make it easy to handle and incorporate into different applications. With its numerous advantages, PI-907 continues to be a reliable solution for UV curing processes in various industries.
