Herculite™ XRV Ultra Flow combines the long-standing expertise of the Herculite brand in an innovative flowable composite. The Smart Placement Technology offered by a rheological additive helps reduce surface tension as the material contacts the tooth surface under pressure – allowing it to flow to the boundaries of the restoration. The same additive encourages higher surface tension after the material has been placed. The formula also guarantees f lexural strength as well as excellent gloss retention and easy polishability.
