Nonenylsuccinic anhydride is widely used as a chemical intermediate in the production of alkyd resins, which are essential in the formulation of paints, coatings, and varnishes. Its ability to react with hydroxyl groups makes it valuable for modifying polymers, enhancing their properties such as adhesion, flexibility, and water resistance. In the paper industry, it is employed as a sizing agent to improve the strength and water repellency of paper products. Additionally, it finds application in the synthesis of surfactants and emulsifiers, which are crucial in various industrial and consumer products. Its reactivity also makes it useful in the production of corrosion inhibitors and lubricant additives, contributing to the durability and performance of metal surfaces and machinery.
