Ethylene Glycol Dimethacrylate (EGDMA) is a difunctional methacrylate monomer used as a crosslinking reagent in polymerization reactions. Its two polymerizable methacrylate groups support the formation of crosslinked polymer networks in resins, coatings, adhesives, hydrogels, and other materials-research formulations.
Synonyms: 1,2-Ethanediol dimethacrylate; Ethylene dimethacrylate.
Product 24896 is a clear, colorless liquid stabilized with 40–80 ppm monomethyl ether hydroquinone (MEHQ). The inhibitor helps stabilize the monomer during storage and should be considered when establishing polymerization conditions.
EGDMA may be used in formulation and polymer synthesis workflows where controlled crosslinking is required. Final material properties depend on the EGDMA concentration, comonomers, initiator system, additives, and curing conditions.

Applications
Crosslinked Polymer Synthesis
EGDMA is used as a difunctional crosslinker in polymerization reactions to form three-dimensional polymer networks.
Hydrogel Research
May be incorporated into hydrogel formulations when a methacrylate crosslinker is needed to establish or adjust network structure.
Coatings & Adhesive Research
Suitable for evaluation in coating, adhesive, and thermosetting resin formulations that use methacrylate polymerization chemistry.
Photopolymer & Composite Resin Research
May be used in photopolymer and composite resin development, including research involving additive-manufacturing and dental-material formulations. Application-specific performance and qualification should be independently evaluated.
Compatibility & Polymerization Considerations
- Designed for use as a reactive crosslinker in methacrylate polymerization systems
- Crosslinking performance depends on concentration, comonomers, initiators, and curing conditions
- Compatibility should be evaluated with solvents, fillers, pigments, and other formulation components
- The MEHQ inhibitor level should be considered when establishing polymerization conditions
Crosslink density can affect properties such as network structure, rigidity, swelling behavior, and solvent resistance. Formulation conditions should be optimized for the intended polymer system and required performance.
Application Tips
- Add at a controlled concentration and mix thoroughly for uniform distribution
- Account for the MEHQ inhibitor when selecting initiator levels and curing conditions
- Evaluate compatibility with all monomers, additives, fillers, and processing solvents
- Use small-scale formulation trials to establish suitable polymerization conditions
Handling & Storage
- Store at 4°C with the container tightly closed
- Keep in a cool, well-ventilated location
- Use only with adequate ventilation and avoid breathing vapor or mist
- Wear protective gloves, protective clothing, and eye or face protection
