Used primarily as a crosslinking agent in dental resins and composite materials, enhancing mechanical strength and durability of dental restorations. It is a key component in light-curable dental fillings, crowns, and adhesives due to its ability to form rigid polymer networks upon curing. Also employed in coatings, inks, and specialty polymers where improved hardness and chemical resistance are required. Its low volatility and good reactivity make it suitable for UV-curable formulations in industrial applications.
