Which of the following statements is true about MMA?

The statement regarding the adhesion properties of MMA (methyl methacrylate) is accurate because MMA is known for its strong bonding capability. It adheres exceptionally well to the natural nail by creating a secure bond, which is enhanced through the process of slight surface "shredding" or etching of the nail plate. This method can create a rougher surface, helping the MMA to grip and adhere more effectively, ensuring longevity in wear.

MMA is not favored for its flexibility. In fact, it is rigid and can lead to more breakage compared to materials like traditional acrylics. It is also not easy to remove; MMA requires professional removal techniques and should not be taken off with standard acetone-based removers, which often leads to damage to the natural nail if not managed properly. Lastly, MMA is not commonly used in regular nail applications, as its use has been largely discouraged in favor of safer alternatives that promote better nail health.
