Onyx 40% Phosphoric Acid Etching Gel applies a suspension of high-contrast, black silicon carbide particles on the tooth surface for enhanced visibility. When scrubbed onto the teeth surface, the etchant particles stay in place and rinse away cleanly for thorough cleaning.

The gel is compatible with any bonding technique or system that requires complete or selective etching and, when agitated, generates a light cleansing and abrasive effect.
