Trihexyl borate is primarily used as a stabilizing agent in various chemical processes, particularly in the production of polymers and plastics. It helps to enhance the thermal stability and durability of these materials, making them more resistant to degradation under high temperatures. Additionally, it is employed as a catalyst or co-catalyst in organic synthesis, facilitating specific reactions such as esterification and polymerization. In the field of lubricants, trihexyl borate is utilized to improve the performance and longevity of oils by reducing friction and wear. It also finds application in the formulation of specialty coatings, where it contributes to improved adhesion and resistance to environmental factors.
