1,4-Butanediol dimethacrylate is widely used as a crosslinking agent in the production of polymers and resins. It is particularly valuable in the manufacture of dental materials, such as dental composites and adhesives, due to its ability to enhance mechanical strength and durability. In the coatings industry, it is utilized to improve the hardness and scratch resistance of protective coatings. Additionally, it serves as a key component in the production of photopolymerizable inks and coatings, enabling rapid curing under UV light. Its application extends to the fabrication of optical lenses and medical devices, where its biocompatibility and optical clarity are advantageous.
