We recommend using Duo-Link Universal with All-Bond Universal.
The bonding protocol is:
1) Use a bonding technique of choice (total etch, self-etch or selective etch)
2) Apply two separate coats of ALL-BOND UNIVERSAL, scrubbing the preparation with an applicator for 10-15 seconds per coat. Do not light cure between coats.
3) Evaporate excess solvent by thoroughly air-drying with an air syringe for at least 10 seconds, there should be no visible movement of the adhesive. The surface should have a uniform glossy appearance; otherwise, apply an additional coat of ALL-BOND UNIVERSAL and repeat Steps 2) and 3).
4) Light cure for 10 seconds.
5) Continue with cementation.
