  • Applications

    4-Vinylbenzaldehyde (CAS 1791-26-0) is a functional monomer used as a building block for polymers and copolymers to manufacture coatings and adhesives, especially where the aldehyde group enables cross-linking or post-polymerization functionalization. It finds use in coatings and inks as a functional monomer for UV-curable or waterborne polymer systems, enhancing adhesion and surface modifiability. With the aldehyde functionality, it also serves as a precursor for the synthesis of functional aromatic compounds in specialty polymers and materials for the plastics and related industries. It can act as an intermediate in the production of other polymer-related chemicals and resins, and is used to enable surface modification and cross-linked networks in applied formulations.
