GG-aenial Universal Flo is a nano-hybrid, light-cured composite that has the easy handling of a low-flow (high viscosity) flowable. Advancements in filler technology led to a new silanation process, resulting in a product that is 69% (by weight) filled with 200 nm homogeneously dispersed particles. It also has thixotropic attributes that allow the material to have easy handling and placement. This flowable also has a beautiful finish and maintains its gloss.
