1.Methacrylic acid is an important intermediate of organic chemical raw materials and polymers.
The most important methyl methacrylate derivative for the production of plexiglass can be used
in the windows of aircraft and civil buildings. It can also be processed into buttons, solar filters and
automotive lamp lenses.
2.the production of coatings with excellent suspension and durability properties, the adhesive made
by it can be used in metal, leather, plastics and building materials, and methyl acrylate polymer lotion
is used as fabric finishing agent and antistatic agent. In addition, methacrylic acid can also be used
as raw material for synthetic rubber, plastic resin, polymer and ester. For example, toughened
glass - methyl methacrylate.
3.For organic synthesis and polymer preparation. It is also used in the manufacture of thermosetting
coatings, synthetic rubber, fabric treatment agent, leather treatment agent, ion exchange resin,
insulating materials and antistatic agents. It is a crosslinking monomer which makes acrylic ester,
lotion and emulsion adhesive, to improve adhesion strength and adhesive stability.
