Mismatched liquid and powder can result in

• A. It speeds up cure.
• B. It makes the product harder.
• C. It can result in unreacted monomer.
• D. It improves bonding.

Answer: (C)

Liquid and powder in nail systems must be compatible so the monomer and polymer react fully. When they’re mismatched, the chemical reaction doesn’t proceed to completion, leaving unreacted monomer trapped in the cured layer. That residual monomer can make the film tacky, softer, and weaker, and it can also cause unpleasant odor and potential irritation. Because the cure depends on the proper chemical pairing, a mismatch disrupts polymerization rather than speeding it up, hardening the surface, or improving bonding. So the most accurate outcome of a mismatch is the presence of unreacted monomer.
