1,6-Hexanediol diacrylate is primarily used as a crosslinking agent in the production of polymers and resins. It is widely applied in the formulation of UV-curable coatings, inks, and adhesives, where it enhances the durability, hardness, and chemical resistance of the final product. In the electronics industry, it is utilized in the manufacture of photoresists and printed circuit boards due to its ability to form strong, stable networks upon exposure to ultraviolet light. Additionally, it finds applications in dental materials, where it contributes to the strength and longevity of composite resins used in restorative dentistry. Its versatility also extends to the production of 3D printing resins, where it improves the mechanical properties and precision of printed objects.
