What is Ethylene dimethacrylate?

Description

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.

Chemical properties

colourless liquid

The Uses of Ethylene dimethacrylate

Ethylene glycol dimethacrylate is a cross-linking methacrylic monomer in dentaI composites, sealants, prostheses, adhesives, artificiaI nails, printing inks, etc.

The Uses of Ethylene dimethacrylate

Ethylene glycol dimethacrylate is used as a functional monomer for polymers and as a cross linking agent between the molecular chains of polymers and elastomers. It is also used in free radical copolymer cross linking reactions. It acts as an intermediate in the production of hydroxyapatite and poly methyl methacrylate composites.

The Uses of Ethylene dimethacrylate

EGDMA can be used in free radical copolymer crosslinking reactions.

What are the applications of Application

Ethylene glycol dimethacrylate is a monomer used to create Hydroxyapatite/Poly methyl methacrylate composites

Definition

ChEBI: Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis(methacryloyl) derivative of ethylene glycol. It has a role as a cross-linking reagent, a polymerisation monomer and an allergen. It is functionally related to an ethylene glycol and a methacrylic acid.

General Description

Ethylene glycol dimethylacrylate (EGDMA) is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol.
