General Description

Ethyl methacrylate (EMA) is an organic compound with the formula CH2=C(CH3)COOCH2CH3. It is a colorless liquid with a pungent odor that is used primarily as a monomer. EMA is a member of the methacrylate ester chemical family. Ethyl methacrylate readily undergoes free-radical polymerization, making it useful for forming high-molecular-weight polymers that are transparent, durable and resistant to many chemicals.

Application

Ethyl methacrylate is used primarily as an ester precursor to acrylic resins, coatings, adhesives and impact modifiers. EMA polymers are used in automobile coatings and sealants for their weather resistance and durability. Dental EMA copolymers are also used as dental adhesives and dental restorative materials. EMA is also used in emulsion polymers to create coatings for paint, textiles, and paper. Thanks to its biocompatibility, EMA finds use in biomedical applications such as bone cements and prosthetics.
