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), 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. Though Ultra-Etch etchant is viscous, it can penetrate into the occlusal fissures or vertical 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. Ultra-Etch etchant can be used for 5 seconds to remove the salts created by etching porcelain.
