  • Applications

    Propane, 2-(ethenyloxy)- (isopropyl vinyl ether, IVE; CAS 926-65-8) is a highly reactive vinyl ether used mainly as a monomer/comonomer in cationic and photo-cationic curing systems for coatings, printing inks and overprint varnishes, adhesives and sealants, where it functions as a reactive diluent to reduce viscosity while contributing to crosslink density, boosting adhesion to metals/glass/plastics, improving flexibility and impact resistance, enabling fast low-temperature cure and low shrinkage; it is also a building block for poly(vinyl ether)s, alternating copolymers with maleic anhydride, and epoxy–vinyl ether hybrid networks tailored for softness, tack and chemical resistance; in organic synthesis, IVE serves for acetal/hemiacetal formation from aldehydes/ketones (carbonyl protection), participates in acid-catalyzed additions (alkoxylation) and cyclic acetal formation (e.g., 1,3-dioxolanes/dioxanes), and acts as an intermediate toward fragrance, pharmaceutical and agrochemical motifs; it is favored as a vinyl-ether functionality carrier in flexible packaging ink formulations, electronics, wood and automotive coatings, and cationically curable 3D-printing resins; in practice it is acid-sensitive and prone to spontaneous polymerization, so it is typically stabilized and handled under controlled storage.
