Etch 'N' Seal combines a 25% phosphoric acid with 0.5% aluminum oxalate so you can etch enamel and condition dentin at the same time. The combined use of Etch 'N' Seal and the Tenure Multi-Purpose Bonding System results in the formation of a dentin hybrid layer that can reduce dentin permeability, protect against acid attack and decrease sensitivity.
