What happens to the bead formed on the brush when monomer liquid is mixed with polymer powder?

When monomer liquid is mixed with polymer powder, a bead forms on the brush that quickly begins to harden due to a chemical reaction known as polymerization. This reaction occurs as the monomer molecules react with each other, creating a network of polymer chains. The mixture transforms from a liquid state into a solid form, which allows for application onto the nails in techniques such as acrylic nails.

The speed of this hardening is crucial in cosmetology, as it determines how the product can be manipulated during application. Knowledge of this process is essential for nail technicians in order to achieve the desired results while ensuring sufficient working time for application.
