Methyl methacrylate adhesives (MMA adhesives) are structural adhesives manufactured based on methyl methacrylate monomer. They are used in various industries such as aviation, automotive and construction. MMA adhesives have many advantages, including high strength, chemical resistance and the ability to cure quickly.

MMA adhesives are a popular choice for structural applications because of their ability to bond metal, plastics and other materials in a durable manner. They offer high tensile strength and good impact resistance, making them ideal for applications with high mechanical stresses. They are also resistant to chemicals, moisture and weather, making them suitable for demanding environments such as aviation or shipbuilding.

MMA adhesives are also popular due to their quick curing. They can cure in just a few minutes, contributing to quick assembly and an efficient production process. They can also harden at low temperatures, which is particularly advantageous for applications in refrigeration technology.

However, there are also some disadvantages of MMA adhesives. They have an unpleasant odor and can be harmful to health if not handled correctly. They are also often more expensive compared to other adhesives.

Overall, MMA adhesives are a popular choice for structural adhesive bonds due to their high strength, chemical resistance and rapid curing. However, they should be treated with caution to avoid health risks.
