  • Applications

    2,6-Distyrenated p-cresol (CAS 1817-68-1) is primarily used as a difunctional styrenic monomer for radical polymerization and as a crosslinking agent in UV-curable coatings, paints, and inks, improving film hardness and chemical resistance. It also serves as an intermediate in the synthesis of specialty polymers and as a building block for rigid, conjugated polymer systems relevant to electronics and optics. Additionally, it is evaluated for use in industrial adhesives and composite formulations where crosslinked networks and thermal stability are desirable.
