Used primarily as a binder and film-forming agent in coatings, adhesives, and sealants due to its excellent flexibility and tack. Commonly found in pressure-sensitive adhesives for tapes and labels, where it provides strong adhesion with low stiffness. Also employed in textile finishes to improve softness and durability, and in paints as a dispersant and thickener for stable, smooth formulations. Its low glass transition temperature makes it ideal for applications requiring elasticity at room temperature. Used in emulsion form for water-based systems, offering environmental and safety benefits over solvent-based alternatives.
