Used primarily as a reactive monomer in the formulation of pressure-sensitive adhesives, especially in tapes, labels, and medical adhesives. Its long alkyl chain provides excellent flexibility, water resistance, and adhesion to low-energy surfaces. Also employed in coatings and sealants where durability and weather resistance are required. Due to its hydrophobic nature, it enhances performance in moisture-resistant applications. Common in acrylic copolymer systems to modify glass transition temperature and improve tack.
