Product Description:

Ethylene glycol dimethacrylate (EGDMA, CAS 97-90-5) is a difunctional methacrylate monomer characterized by two reactive methacrylate groups linked by an ethylene glycol spacer. It is a clear, colorless to pale yellow liquid with a characteristic ester odor. Its chemical structure makes it a versatile crosslinking agent. The primary and most significant application of EGDMA is in the polymer industry. It is widely used as a crosslinker in the production of various polymers and copolymers. It imparts rigidity, hardness, and thermal stability to the final polymer network. Key applications include the manufacture of acrylic resins, dental materials (e.g., denture bases, restorative composites), contact lenses, ion-exchange resins, chromatographic media, and as a component in coatings, adhesives, and inks. Its ability to form highly crosslinked, three-dimensional networks is central to its utility. EGDMA is also employed in biomedical research for creating hydrogels and molecularly imprinted polymers (MIPs). It is a skin and eye irritant and may cause allergic skin reactions. Proper handling with personal protective equipment is essential due to its potential toxicity and ability to polymerize exothermically.
