Ultra-Etch is available as a viscous, 35% phosphoric acid gel. The optimum level of viscosity, along with use of the Blue Micro or Inspiral Brush tip, facilitates precision placement and superior control.
Ultra-Etch is viscous enough to prevent migration on a vertical surface. However, it can penetrate into the smallest fissures of occlusal surfaces due to physical and chemical properties which promote capillary action. The optimum viscosity maintains a thick enough layer to prevent premature drying. Etch rinses away quickly with air/water spray.

• Ideal viscosity.
• The fumed silica etchant that rinses off clean.
• Ideal dentine etching results.
• The only self-limiting phosphoric acid dentine etchant.
