Ethyl Methacrylate (EMA)

Ethyl Methacrylate, with the chemical formula CH₂=C(CH₃)COOCH₂CH₃, is an important acrylic ester monomer. It appears as a colorless transparent liquid with a characteristic ester odor. It is a reactive vinyl monomer capable of forming high molecular weight polymers through free radical polymerization. This product is mainly used in the production of various acrylic resins, coatings, adhesives, etc., offering excellent transparency, weather resistance and mechanical properties.
