Ultra-Etch™

Etchant

Ultra-Etch etchant 35% phosphoric acid solution features ideal viscosity, facilitates precise placement and superior control. It is self-limiting in its depth of etch (average depth of 1.9 μm with 15-second etch),1 creating an etch pattern that adhesives can penetrate for increased bond strength. Studies demonstrate Ultra-Etch etchant’s unique self-limiting chemistry on dentin creates an optimal surface to receive resin.2 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 that is thick enough to prevent premature drying.


Ultra-Etch etchant is indicated for use on dentin and enamel to create optimal bonding surfaces. It can also be used to remove porcelain salts prior to silane of bonding agent.

  • Self-limiting1 on dentin
  • Penetrates smallest fissures and won’t run on a vertical surface
  • Precise placement
  • Rinses cleanly—leaves no residue

Note: Do not use phosphoric etchant on metals or zirconia, as this will reduce bond strength.
