Widely used as a photoinitiator in UV-curable systems, this compound plays a key role in initiating free radical polymerization upon exposure to ultraviolet light. It is especially effective in clear coatings, inks, and adhesives where fast curing and surface hardness are required. Due to its ability to cure quickly under low-intensity UV light, it is favored in formulations for printing, electronics, and dental materials. Its low yellowing properties make it suitable for applications requiring optical clarity and color stability. Additionally, it is often used in combination with other photoinitiators to enhance curing depth and efficiency in thick or pigmented films.
