•   Self-limiting

•   Penetrates smallest fissures but won’t migrate on a vertical surface

•   Increases bond strength and reduces sensitivity

•   Places precisely

•   Rinses cleanly—leaves no residue. Ultra-Etch 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.
