Hydrogenated dimer acid is widely used in the production of high-performance polyamide resins, which are essential in coatings, adhesives, and inks. Its excellent thermal stability and flexibility make it a key component in hot-melt adhesives, particularly for packaging and woodworking applications. Additionally, it is utilized in the formulation of corrosion inhibitors for lubricants, enhancing their protective properties. In the personal care industry, it serves as an emollient and stabilizer in skincare products, providing smooth texture and improved shelf life. Its versatility also extends to the production of synthetic lubricants, where it improves viscosity and wear resistance.
