Which type of acrylic monomer has very good adhesion to the natural nail plate?

The choice of methacrylates as the correct answer is based on their superior adhesion properties to the natural nail plate. Methacrylates, including commonly used materials in nail enhancements, form strong bonds with keratin found in the nail, leading to effective adhesion and longevity of the application. This characteristic makes methacrylates a preferred choice in both professional nail services and at-home nail products.

In contrast, other types of acrylic monomers may not demonstrate the same level of adhesion. For example, cyanoacrylates, while they do bond quickly, are not typically used in nail enhancements because their bond is more suited for bonding skin or for quick repairs rather than for creating durable nail enhancements. Methyl methacrylate (MMA), although it has strong adhesion, is less favored in many professional nail salons due to safety and health concerns, as it can cause irritation and allergic reactions. Oligomers contribute to the formulation of certain nail products but do not specifically highlight the strong adhesion properties that methacrylates offer.

This understanding of the properties of these monomers is crucial for nail technicians to ensure the best outcomes for their clients and to choose the appropriate products for different nail applications.
