Di(ethylene glycol) dimethacrylate is widely used as a crosslinking agent in the production of polymers and resins. Its primary application is in the formulation of dental materials, where it enhances the durability and strength of dental composites and adhesives. Additionally, it is utilized in the manufacturing of coatings, inks, and adhesives, providing improved flexibility and resistance to wear. In the field of optics, it is employed in the production of lenses and optical fibers due to its ability to form clear, stable polymers. The chemical also finds use in the creation of hydrogels for medical applications, such as drug delivery systems and contact lenses, owing to its biocompatibility and water-absorbing properties.
