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. Ultra-Etch etchant is self-limiting
in its depth of etch (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
