PS 48 is commonly used as a photoinitiator in UV-curable coatings and inks. It plays a crucial role in initiating the polymerization process when exposed to ultraviolet light, enabling rapid curing of coatings on various substrates like paper, plastic, and metal. This makes it valuable in industries such as packaging, printing, and electronics, where fast and efficient curing is essential. Additionally, PS 48 is utilized in the production of adhesives and composite materials, contributing to improved durability and performance in end products. Its ability to enhance the efficiency of UV curing processes makes it a key component in modern manufacturing techniques.
