Used as a cationic monomer in the synthesis of functional polymers, particularly in producing positively charged coatings and films. Commonly applied in water treatment as a flocculant due to its ability to bind negatively charged particles and impurities. Employed in personal care products, such as conditioners and hair styling agents, where it provides antistatic properties and improves adhesion to hair and skin. Also utilized in the preparation of ion-exchange resins and in biomedical applications like drug delivery systems, where controlled surface charge enhances biocompatibility and targeting. Its reactivity in free radical polymerization makes it valuable in creating specialty adhesives and coatings with improved wet strength and durability.
