Chemical Description

  • Hydroxyethyl methacrylate (HEMA) is a monomer that is used for making polymers. These polymers that are made by HEMA are hydrophobic in nature.
  • HEMA is colorless and liquid in nature, the boiling point is at 67 degrees Celsius and the melting point stands at -12 degrees Celsius. They must be stored in temperatures ranging between 2-8 degrees Celsius.
  • HEMA is mainly used in the manufacturing of fiber treating agents, thermosetting coatings, adhesives and medical polymer materials.
  • When the polymers made using HEMA come in contact with water they swell or bubble up because of the molecule pendant group present in them.
  • The polymers created by HEMA are also capable of absorbing a range of 10 to 600 percent of water they come in contact with, the water absorbing percentage of these polymers completely depends upon their physical and chemical structures.
  • The ability of the polymers to absorb water has resulted in the making of the very first materials to be used to manufacture flexible contact lenses.
  • HEMA can also be used in the making of coating for high-end cars by the reaction caused by mixing it with melamine and epoxy resin.
  • It can also be used for today’s very famous and well-known 3D printing as it cures very quickly at room temperature when HEMA is exposed to ultraviolet light.
  • HEMA does not cause any serious injuries when exposed to bare skin but it is mildly irritating and can cause allergic reactions to the skin such as itching, blistering, hives and burning.
  • The chemical formula for HEMA is C6H10O3 with a molecular weight of 130.1418.
  • The other infamous uses of HEMA include electron microscopy, light microscopy and acrylic resin which is a useful component in making certain paints.
  • Hydroxyethyl methacrylate (HEMA) is a monomer widely used in the production of polymers. These polymers exhibit hydrophobic properties, making them suitable for various industrial and medical applications.
  • Polymers created with HEMA swell or bubble up upon contact with water due to the pendant groups in their molecular structure.
  • HEMA is used in electron microscopy and light microscopy due to its favorable properties.
