  • Applications

    2-Allyloxyethanol is primarily used as a reactive intermediate and functional monomer in polymer and resin synthesis. It is commonly evaluated as a reactive diluent and crosslinkable modifier for UV-curable coatings and inks, enabling incorporation of allyl functionality into resins. It also serves as a building block for hydroxyl-containing polymers (e.g., polyethers, polyurethanes, and acrylates) and as a precursor to other specialty monomers used in adhesives and sealants. Additionally, the hydroxyl and ether functionalities provide handles for further chemical modification in specialty resins and plastics formulations, making it useful in coatings, plastics, and adhesive applications, subject to formulation limits and local regulations.
