Synonym: Ethylene Glycol Monomethacrylate

2-Hydroxyethyl Methacrylate is a hydroxyester compound and a resin monomer used in desensitizing dentin. By applying 2-hydroxyethyl methacrylate locally to sensitive teeth, sensitive areas in the teeth get sealed and block the dentinal tubules at the dentin surface from stimuli that cause pain. This prevents excitation of the tooth nerve and relieves pain caused by tooth hypersensitivity.

2-hydroxyethyl methacrylate is an enoate ester that is the monomethacryloyl derivative of ethylene glycol. It has a role as a polymerisation monomer and an allergen. It derives from an ethylene glycol and a methacrylic acid.

(Hydroxyethyl)methacrylate
Hydroxyethylmethacrylate or HEMA is the organic compound with the formula H2C=C(CH3)CO2CH2CH2OH. It is a colorless viscous liquid that readily polymerizes. HEMA is a monomer that is used to make various polymers.

Applications
Polyhydroxyethylmethacrylate is hydrophobic; however, when the polymer is subjected to water it will swell due to the molecule's hydrophilic pendant group. Depending on the physical and chemical structure of the polymer, it is capable of absorbing from 10 to 600% water relative to the dry weight. Because of this property, it was one of the first materials to be successfully used in the manufacture of soft contact lenses.[3]

When treated with polyisocyanates, poly(HEMA) makes a crosslinked polymer, an acrylic resin, that is a useful component in some paints.

Use in 3D printing
HEMA lends itself well to applications in 3D printing as it cures quickly at room temperature when exposed to UV light in the presence of photoinitiators. It may be used as a monomeric matrix in which 40nm silica particles are suspended for 3D glass printing.[5] When combined with a suitable blowing agent such as BOC Anhydride it forms a foaming resin which expands when heated

Storage & Handling:
To prevent polymerization, 2-Hydroxyethyl Methacrylate (2-HEMA) should always be stored in air, and never under inert gases. For the stabilizer to work effectively, oxygen is required. It must contain a stabilizer. Storage temperature should not exceed 35 °C. Under these conditions, the storage stability of one year can be expected. To minimize the likelihood of congestion, the storage procedure should strictly follow the principle of “first come, first come”. For a long shelf life of more than 4 weeks, it is advisable to replenish the oxygen content. Over time, the content of ethylene glycol diacrylate slowly increases. If this component is relevant to your process, 2-HEMA should be used within 6 months of receipt. The preferred material for tanks and pipes is stainless steel. Carbon steel is also used, although rust formation may occur, which will lead to a problem with product quality (color). Iron (III) -ion has been shown to be a weak initiator of polymerization. If carbon steel is to be used, special treatment should be used to prepare the tank for use. Storage tanks, pumps, and pipes must be earthed.

Safety
2-Hydroxyethyl Methacrylate (2-HEMA) is a combustible substance. At the temperatures above 97 °C, it can form explosive mixtures of vapor with air. The substance is irritating to the eyes, skin and respiratory tract. If this fluid is swallowed, aspiration into the lungs can lead to chemical pneumonitis. The flash-point is 97 °C [https://www.ilo.org/dyn/icsc/showcard.display?p_lang=en&p_card_id=1724&p_version=2]. When working with 2-HEMA, sanitary rules for organizing technological processes and hygienic requirements for production equipment must be strictly observed. All types of work with 2-Hydroxyethyl Methacrylate (2-HEMA) should be carried out in rooms equipped with general supply and exhaust ventilation. It is not allowed to carry out work in these rooms using an open fire. Those working with 2-HEMA must be provided with special clothing and personal protective equipment. In case of fire, it is necessary to use fire extinguishers OP-5, OVP-100 koshma, sand, asbestos cloth. Spread on solid soil 2-Hydroxyethyl Methacrylate (2-HEMA) should be covered with sand.
