The main purpose

Used in organic synthesis and polymer preparation. Can be used as a raw material for synthetic rubber. Manufacture thermosetting coatings, synthetic rubbers, fabric treatment agents, etc. It is a monomer for the manufacture of acrylate solvent-based and emulsion-based adhesives to improve the bonding strength and stability of the adhesive. Manufacturing paints, insulating materials, adhesives and ion exchange resins. Used as an organic reagent, it is an important organic chemical raw material and polymer intermediate. The plexiglass produced by its most important derivative product methyl methacrylate can be used for windows of airplanes and civil buildings, and can also be processed into buttons, solar filters and automotive lamp lenses; the produced coatings have superior suspension and rheology And durable properties; the prepared adhesive can be used for the bonding of metal, leather, plastic and building materials; methacrylate polymer emulsion is used as a fabric finishing agent and antistatic agent. In addition, methacrylic acid can also be used as a raw material for synthetic rubber.
