- The Nano-clusters allow deeper and greater depth of cure thus having greater strength, almost negligible uncured
resin, and lesser polymerization shrinkage.
- The ingredients of Nano–Cluster Flowable Composites tend to have more translucence and therefore better and
greater aesthetics (Contains: BisGMA, TEGDMA, Procrylat) .

- The last incremental layer of Nano-Cluster can be manipulated to form Cuspal inclines.
- Almost a decade ago, it was recommended to apply a thin layer of flowable composites to take the advantage of its
wettability, before placing paste form composite in a cavity to decrease the shearing effect of the first layer of paste
form composite on light curing, on the walls of the cavity. Using Flowables incrementally will allow less shrinkage stress
and almost the same strength as Paste form Composites.
