IND Dipping Liquid - #3 Activator is a clear, odorless liquid that is used to harden and seal the final layer of dip powder. It is applied after the last layer of powder has been dipped, and before the top coat is applied. The activator works by reacting with the polymer in the powder, causing it to cross-link and harden. This creates a durable and long-lasting finish. IND Dipping Liquid - #3 Activator is easy to use. Simply apply a thin coat to each nail, using a brush or a dipping cup. Be sure to coat the entire nail, including the free edge. Allow the activator to dry completely before applying the top coat.
