Kuraray Noritake's NEW Esthetic Colorant specially developed for "KATANA™ Zirconia" Multi-Layered series to perfectly complement the effects obtained from the materials' multi-layered color structure with maintaining the original strength of zirconia. Available in 12-shade, simply apply to the restoration after milling using a metal-free brush or a dedicated Liquid Brush Pen developed for easy control of characteristics. Esthetic Colorant diffuses into the pre-sintered structure and is fixed during sintering with no additional baking, resulting in lifelike shade effects shining from within the restoration.
