If monomer is contaminated, what is the likely outcome?

• A. Stronger bond
• B. Lifting and/or breaking
• C. No effect
• D. Faster cure

Answer: (B)

Contamination of monomer disrupts the polymerization process, weakening the bond between the nail enhancement and the natural nail. Impurities such as moisture, oils, or residues interfere with how the monomer reacts and cross-links with the powder, so the forming layer doesn’t set properly or fully cure. The result is a weak, unstable bond that tends to lift from the nail bed and can crack or break with normal wear. Faster cure or a stronger bond wouldn’t occur because the contaminants hinder, not help, the chemical reaction. No effect isn’t accurate either, since contamination changes how well the system cures and adheres.
