Rubber Sep is a latex liquid that creates a peelable film. It is a die spacer, release agent and separator for acrylic and composite resin restorations. Paint a thin coat onto a preparation and let it dry which takes a few minutes. The pink Rubber Sep dries translucent red and white Rubber Sep dries clear. The prep now has a 12 micron coating that allows the resin to cure onto the surface, making the cured resin easier to remove.
