Hydroxyethyl methacrylate hema 868-77-9
Price: contact
2-Hydroxyethyl methacrylate is used in UV curable inks and coatings. It is also used in adhesives, artificial nails, dental materials and varnishes. In dentistry, it is one of the major volatile acrylates along with methyl methacrylate. In addition, it is used as a monomer in the synthesis of dental restorative polymers and geotechnical grouting polymers in construction engineering.

| definition | 2-Hydroxyethyl methacrylate is an acrylic acid ester and a monomethacryloyl derivative of ethylene glycol. |
| general instructions | 2-Hydroxyethyl methacrylate (HEMA) is inherently biocompatible. Polymeric hydrogel scaffolds can be produced by polymerizing HEMA in water. |
| adventure | Class 30% (contains xylene): Flammable, moderate fire risk. |
| Purification method | The ester was dissolved in water and extracted with n-heptane to remove ethylene glycol dimethacrylate (checked by gas-liquid chromatography and NMR) and distilled twice under reduced pressure [Strop et al., 2007]. Journal of Physical Chemistry 80 694 1976]. [Beilstein 2 IV 1530. ] |
