Super Etch is a 37% wt phosphoric acid etchant for enamel and dentin. Super Etch's high viscosity and easy to control ?ow allows precise placement. It is perfect for selective enamel etching procedures and has a high visibility for precise selective placement of its non-slump gel. Simply agitate the gel to lower its viscosity. Super Etch creates micropores in the enamel surface and removes the smear layer to unblock dentinal tubules. Promotes adhesive resin penetration and resin tag formation.
