Description and Uses

Ethyl Methacrylate is the ester of ethyl alcohol and methacrylic acid. Other chemical names for this compound are Ethyl 2- Methyl-2-Propenoate; 2-Methyl-2-Propenoic Acid, Ethyl Ester; 2-Propenoic Acid, 2-Methyl-, Ethyl Ester; and Methyacrylic Acid, Ethyl Ester. It is a colorless liquid with a melting point below -75℃, a boiling point of 119℃, and a specific gravity of 0.911. It has a molecular weight of 114.14 Da, a refractive index (n, 25/D) of 1.4116, and a flash point (OC) of 70℃. Ethyl Methacrylate has an acrid acrylate odor and is soluble in alcohol and ether. It is readily polymerized and is chemically reactive. Ethyl Methacrylate monomer is very hydrophobic and poorly “wets” the hydrophilic keratin surface of the nail plate, requiring hydrophilic nail primers and additives to obtain sufficient adhesion[1].

Ethyl methacrylate can be manufactured via a reaction of methacrylic acid or methyl acrylate with ethanol. It is used primarily for manufacturing polymers and as a component of acrylic polymers for surface coatings and as a structural monomer for some artificial fingernail formulations.
