Product Description:
Used as a photoinitiator in UV-curable systems such as inks, coatings, and adhesives. It generates free radicals upon exposure to ultraviolet light, initiating polymerization of monomers and oligomers. Commonly applied in printing inks for packaging and labels due to its efficiency in dry film and low migration properties. Also utilized in some photoresists and imaging materials where high resolution and stability are required. Shows good compatibility with acrylate-based formulations and works effectively under low-intensity UV sources.
