12-Hydroxy Stearic Acid (12-HSA) plays a crucial role in various industrial applications. It’s extensively used in the formulation of glycerine-free multi-purpose calcium and lithium-based lubricating greases, providing excellent water resistance and mechanical stability. Additionally, 12-HSA is vital in the production of thixotropic agents for solvent-based coating systems, which enhance the viscosity and stability of coatings. In the paint industry, it contributes to the production of solvent or waterborne polyesters, offering superior film-forming properties and durability. Furthermore, 12-HSA is an essential component in the manufacture of wax blends and hot melt adhesives, improving their flexibility and adhesive strength. It also serves as a valuable processing aid for natural and synthetic rubber, enhancing their performance and durability.
