3,6-DIOXAHEPTYL ACRYLATE (CAS:7328-18-9) is a versatile low-viscosity functional acrylate monomer characterized by two internal ether linkages in its molecular backbone, a structure that gives it a unique combination of moderate hydrophilicity, enhanced flexibility, and strong compatibility with both polar and non-polar polymer matrices. This monomer is most widely used as a reactive diluent in UV- and electron beam-curable formulations, including industrial protective coatings, pressure-sensitive adhesives, printing ink binders, and low-volume composite resin systems. Unlike inert diluents that evaporate and leave defects after curing, it participates in the crosslinking reaction, so it can reduce the overall viscosity of a formulation to improve processability without sacrificing crosslinking density or the long-term mechanical strength of the final cured product.

Its polar ether groups also boost adhesion to a wide range of common substrates, including glass, treated metals, cellulose-based materials, and polar engineering plastics, making it a popular additive for durable coating formulations that require strong bonding even under high-humidity conditions. For industrial and research use, it is available in both bulk industrial grades for large-scale manufacturing and purified small-quantity samples for laboratory R&D. It should be stored in sealed containers in a cool, dark area away from free radical initiators and high heat to prevent unintended premature polymerization. Recent advancements in green polymer chemistry have also highlighted its potential as a sustainable co-monomer, as new production routes can synthesize it from renewable feedstocks to lower the carbon footprint of end curable materials.
