Description
Tetraethylene glycol dimethacrylate is a crosslinking
agent of acrylic resins, employed to optimize the
dilution of high-viscosity monomers and to link
together the macromolecules costituting the polymer,
to make their three-dimentional structure more rigid.
Occupational dermatitis was reported in a dental
technician.
Chemical Properties
Water-white to pale-straw liquid. Insoluble in water;
soluble in styrene, many esters, and aromatics;
limited solubility in aliphatic hydrocarbons. Combustible.
Uses
High purity PEG dimethacrylates are commonly used in PEG-based hydrogels and crosslinking hydrophilic polymers.
Uses
methacrylate present in adhesives; in polyethyleneglycol dimethacrylate in Loctite anaerobic sealants.
Hazard
Irritant to skin and eyes.
