The ultra-Etch etchant is a 35% phosphoric acid solution. It features ideal viscosity, which, along with the use of the Blue Micro™ or Inspiral™ Brush tip, facilitates precision placement and superior control. The ultra-Etch etchant is self-limiting in its depth of etching (average depth of 1.9μm with 15-second etch), creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Studies demonstrate that Ultra-Etch etchant’s unique self-limiting chemistry creates an optimal surface to receive resin. Though Ultra-Etch etchant is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action. Its ideal viscosity maintains a layer thick enough to prevent premature drying.
- Self-limiting
- Penetrates smallest fissures but won’t migrate on a vertical surface
- Increases bond strength and reduces sensitivity
- Places precisely and rinses clearly
- Rinses cleanly—leaves no residue
