Anwendungen & Verwendung
Beschreibung
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.
