Ethyl methacrylate is a clear, colorless, and highly flammable liquid that polymerizes but at a slower rate than that of the parent acrylate.
Uses
Ethyl methacrylate can be manufactured via a reaction of methacrylic acid or methyl acrylate with ethanol.
Ethyl Methacrylate 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.
Ethyl methacrylate is used in dental protheses or in photobonded sculptured nails.
