Used as a reactive co-monomer in emulsion polymerization processes, particularly in the production of latex paints and coatings. It improves film formation and enhances water resistance by participating in crosslinking reactions at ambient temperatures. Commonly employed in adhesives, textile finishes, and paper coatings where improved durability and adhesion are required. Its functional group allows for covalent bonding with other resins, increasing the toughness and chemical resistance of the final product. Also utilized in specialty polymers that need flexibility and long-term stability under varying humidity conditions.
