Why is monomer used with acrylic powder?

The acrylic powder is formed from the reaction of the monomer liquid with the polymer powder. The monomers in the liquid are small chemical units that react when they’re mixed with the chemicals in the powder. This enables the acrylic to set and it's the reason why you don't need to cure it under a UV lamp.
