Kryolan Flexible Sealer is a clear synthetic liquid used for protection over latex, foam, wax models, putty noses, chins and other prosthetic pieces. Use a brush to apply the preparation thinly over wax models, and for a distance of 1 cm beyond the model onto the bordering skin. Allow to dry, and then apply powder. As needed, Kryolan Sealer can be diluted with Kryolan Spirit Gum Remover or alcohol.
