CLEARFIL SE Protect is a 2-step, light-cure bonding system, consisting of an antibacterial (MDPB monomer) self-etching primer and a fluoride-releasing bonding agent. It is easy to use, has minimal dentin decalcification, high bond strength, and lower post operative sensitivity. For direct fillings, use primer with bond: Apply PRIMER to the entire cavity wall, leave it in place for 20s, mildly air-dry, apply BOND, mildly air-dry, light-cure 10s. For indirect / core build-ups, mix Primer with Clearfil DC Activator. Storage: refrigerated 2-8°C; should be brought to room temperature before using. Package contains 1x 6ml Clearfil SE Protect Primer.
