Used primarily as a monomer in the production of polyvinylpyrrolidone (PVP), it serves as a key component in adhesives, coatings, and inks due to its excellent film-forming and binding properties. Widely applied in pharmaceuticals as a binder in tablets and as a solubilizer for active ingredients. Also utilized in personal care products like hairsprays, where it provides hold and humidity resistance. Its water solubility and biocompatibility make it suitable for medical applications such as wound care dressings and drug delivery systems. Additionally, it functions as a dispersing agent in various industrial formulations and is used in UV-curable coatings due to its rapid polymerization under UV light, enabling efficient high-speed production.
