What is Ethylene glycol dimethacrylate?
Ethylene glycol dimethacrylate (CAS 97-90-5), commonly abbreviated as EGDMA, is a bifunctional methacrylate monomer used as a crosslinking agent in polymer systems.
Where is Ethylene glycol dimethacrylate used?
- Industrial cured networks: covalent bridges between polymer chains, improving mechanical strength, solvent resistance and dimensional stability
- Acrylic and methacrylic resins: controls network density, tuning hardness and swelling in contact lenses and dental composites
- Adhesives and sealants: cohesive strength and chemical resistance in structural bonding and specialty optical materials
- UV-curable coatings for printing and packaging: faster cure response and surface hardness on films, labels and flexible substrates
- In suspension and emulsion polymerization it produces ion-exchange resins and controlled-release polymer beads for filtration.
Good to know: Typically stabilized with a polymerization inhibitor such as MEHQ for safe storage and transport.
Commercial specifications
- Purities of 98% and higher
- Technical and high-purity grades
