Etching a tooth is an important part of the bonding process, but some etchants are hard to control. Ultra-Etch etchant was designed with the ideal viscosity to give you a smooth and precise delivery. Etch exactly where you want and never where you don’t.

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. Ultra-Etch etchant's unique self-limiting chemistry on dentin creates an optimal surface to receive resin.2, 3, 4 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.
