For professionals in the chemical industry, understanding the precise properties and applications of key materials is crucial for successful product development and procurement. Photoinitiator 907, identified by CAS number 71868-10-5, is a vital component in the realm of UV-curable systems. This article serves as a comprehensive guide for B2B buyers, R&D scientists, and formulators looking to source and utilize this essential chemical auxiliary.

Photoinitiator 907 is a Type I free radical photoinitiator with a molecular formula of C15H21NO2S and a molecular weight of approximately 279.4. It typically presents as a white powder, with a melting point range of 70-75°C. Its chemical structure and absorption characteristics in the UV spectrum make it exceptionally efficient for initiating photopolymerization reactions. When exposed to UV light, it undergoes photocleavage to generate reactive species that rapidly cure unsaturated prepolymer systems, such as acrylic resins and vinyl monomers. This makes it an indispensable ingredient for manufacturers aiming for swift and effective curing processes.

The applications of Photoinitiator 907 are diverse and span multiple industries. It is widely employed in UV-curable coatings for wood, plastic, and metal, providing fast drying times and durable finishes. In the printing industry, it enhances the performance of UV-curable inks used in packaging, labels, and graphic arts, ensuring high print quality and resistance. Furthermore, its utility extends to UV-curable adhesives, electronic components, and even specialized applications like optical fiber coatings. The compound's low volatility and low odor are also beneficial properties for formulators and end-users.

For B2B buyers, understanding the supply chain and identifying reliable manufacturers is key. Sourcing Photoinitiator 907 from established suppliers in China offers access to high-purity products at competitive prices. When inquiring about this product, it's important to specify purity requirements, desired quantities, and packaging needs. Key considerations for procurement include the supplier's production capacity, quality control measures, and compliance with international standards. Seeking quotes from multiple reputable suppliers will help in securing the best terms and ensuring a consistent supply for your manufacturing operations.

In essence, Photoinitiator 907 (CAS 71868-10-5) is a high-performance chemical that offers significant advantages in UV curing applications. By understanding its properties and carefully selecting a trusted supplier, businesses can leverage this photoinitiator to enhance product quality, improve process efficiency, and gain a competitive edge in their respective markets. If you are looking to buy this product, consider its excellent performance in both clear and pigmented systems, and seek out a supplier that can meet your specific technical and commercial requirements.
