Blue tint gel: High visibility for precise placement. No interference with adhesive: Super Etch inorganic silica gel thickener is no obstacle to the adhesive. Other etchants block adhesives with a wax-like polymer residue which can inhibit penetration and bonding. Thixotropic gel: Super Etch non-slump gel offers precise placement. Agitate the gel to lower its viscosity. Super Etch: Super Etch creates micropores in the enamel surface and removes the smear layer to unblock dentinal tubules. It promotes adhesive resin penetration and resin tag formation.
