Trimethylolpropane trimethacrylate is widely used in the production of coatings, adhesives, and sealants due to its ability to form durable, cross-linked polymer networks. It is a key component in UV-curable inks and coatings, providing excellent adhesion, hardness, and chemical resistance. In the dental industry, it is utilized in composite resins and restorative materials, offering high strength and stability. Additionally, it is employed in the manufacture of optical lenses and fiber optics, where its clarity and refractive properties are essential. Its cross-linking capabilities also make it valuable in the production of high-performance plastics and elastomers.
