2-Hydroxy-Ethyl Methyl Acrylate (2-HEMA)

2-Hydroxy-Ethyl Methyl Acrylate (2-HEMA) is an organic compound with the molecular formula C6H10O3 and it’s the most used neutral hydrophilic monomer.. It is a viscous clear, soluble, colorless liquid, with a pungent, sweet odor, that readily polymerizes. its homopolymer is water-insoluble but plasticized and swollen in water.The product contains low levels of methacrylic acid and ethylene oxide.

Production

2-HEMA is produced by reacting ethylene oxyde and a methacrylic acid.

Uses

HEMA is a monomer that is used to make various polymers. It’s used in the manufacture of acrylic polymers for coatings for automotive, adhesives, printing inks, appliance, and metal applications.

HEMA is used to synthesize hydrogel products such as soft contact lenses, as well as polymer binders for controlled drug delivery applications.
