Tetraethylene glycol dimethacrylate is widely used as a crosslinking agent in the production of polymers and resins. It enhances the durability, strength, and flexibility of materials, making it valuable in dental composites, adhesives, and coatings. In dentistry, it is a key component in restorative materials and sealants due to its ability to form strong, stable bonds. Additionally, it is utilized in the manufacturing of contact lenses and other optical devices, where its properties contribute to clarity and biocompatibility. In industrial applications, it is employed in the creation of high-performance coatings and inks, providing resistance to wear and environmental factors. Its versatility also extends to the production of hydrogels used in medical and pharmaceutical fields for drug delivery systems and wound care products.
