Monomer
The liquid half of acrylic, which hardens the powder it is mixed with.
Monomer is what the brush is dipped into. The ratio it picks up against the powder is the whole craft: too wet and the bead runs into the cuticle, too dry and it drags and leaves bubbles.
It has a strong smell and should always be worked under ventilation.
Also called: liquid, acrylic liquid
