Ultra-Etch is a viscous 35% phosphoric acid solution. The optimal level of viscosity, along with the use of the Blue Micro tip or Inspiral Brush tip, facilitates precision placement and superior control. Contemporary studies demonstrate Ultra-Etch is the optimum "total etch" etchant. Ultra-Etch is just viscous enough to prevent migration on a vertical surface. However, it can penetrate into the smallest fissures of occlusal surfaces due to physical and chemical properties that promote capillary action. The optimum viscosity maintains a thick enough layer to prevent premature drying.
