Used primarily as a plasticizer in polymers, especially in coatings, adhesives, and sealants. It improves flexibility and durability of films while maintaining good low-temperature performance. Commonly found in water-based systems due to its solubility and compatibility with acrylic and vinyl emulsions. Also employed in textile finishes and printing pastes for enhanced softness and adhesion. Offers lower volatility and better hydrolytic stability compared to some phthalate plasticizers, making it suitable for applications requiring longer service life and reduced migration.
