Description and Uses

The crosslinking agent of acrylic resins, ethyleneglycol dimethacrylate (EGDMA), is employed to optimize the dilution of high-viscosity monomers and to link together the macromolecules costituting the polymer. It caused contact dermatitis in dental technicians and dental assistants. A case was also reported in a car rear-view mirror manufacturer.

It is used as a monomer to prepare Hydroxyapatite/Poly methyl methacrylate composites. 1
EGDMA can be used in free radical copolymer crosslinking reactions.
