Clinician's Choice® Max Etch has a 35% concentration of phosphoric acid, which represents the gold standard in achieving a consistent, micro-mechanically retentive enamel and dentin surface for virtually all bonding procedures.

The flowability and rich blue colour of Max Etch allows for precise placement, including occlusal grooves, yet it is viscous enough to prevent migration. Max Etch is also self-limiting in its depth of etch (average depth of 1.9μ with 20-second etch).

In addition, Max Etch rinses quickly leaving behind a clean, etched surface with no residual pigment or filler to affect the adhesive integrity.
