Etch-Rite™ 38% Phosphoric Acid is a soft, thixotropic gel with handling characteristics most preferred by clinicians. It dispenses through small gauge needles, stays where placed, washes off with ease, and provides the optimal etch pattern on dentin and enamel surfaces to ensure mechanical retention of bonding agents, restorative resins and resin cements. The blue gel is easily visible and the material is available in a wide variety of packaging options.
