Used as a reactive diluent and comonomer in radiation-curable coatings, inks, and adhesives. Its vinyl ether group enables fast curing under UV light, providing low viscosity and reduced shrinkage during polymerization. Offers excellent clarity and flexibility in final products. Commonly employed in electronics, printing, and specialty coatings where low odor and good adhesion are required. Also acts as a protecting group in organic synthesis due to its acid-sensitive nature, allowing selective deprotection in complex molecule assembly.
