- Ultra-etch etchant is a 35% phosphoric acid solution for use on dentin and enamel to create ideal bonding surfaces. - Ultra-etch etchant is self-limiting in its depth of etch thus creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. - Combined with an ideal viscosity that facilitates precise placement, this unique self-limiting chemistry results in an optimal surface to receive resin. **For further product information , please contact Chat Support**
