Product Description:

Triethylene glycol dimethacrylate (TEGDMA, CAS 109-16-0) is a difunctional methacrylate monomer characterized by two reactive methacrylate groups connected by a triethylene glycol spacer. It is a clear, colorless to pale yellow liquid with low viscosity and a molecular weight of 286.32 g/mol. Its primary application is as a key crosslinking agent and reactive diluent in the production of various polymers. It is extensively used in dental restorative materials (composite resins and adhesives), UV-curable coatings, inks, and adhesives. The presence of two methacrylate groups allows it to form highly crosslinked polymer networks upon free-radical polymerization (often photoinitiated), imparting hardness, strength, and chemical resistance to the final material. It is also used in the manufacture of contact lenses and as a component in some specialty polymer formulations. TEGDMA is known to be a potential skin and eye irritant. In dental applications, residual unreacted monomer can leach out and has been associated with biocompatibility concerns, including allergic reactions and cytotoxicity. Proper handling with personal protective equipment is recommended.
