GRADIA DIRECT Flo:
Designed to be used in combination with GRADIA DIRECT, its physical properties, proper flow characteristics and direct application make this material ideal as a liner under composite restorations. Gradia Direct Flo’s non-sticky formula shapes perfectly to cavity
walls and makes it easy to handle.
GRADIA® DIRECT Flo is a light-cured, highly flowable, fluoride releasing composite.
Very low viscosity for easy, fluid placement as a liner, base or resin sealant, GRADIA DIRECT Flo is radiopaque, contains fluoro-alumino-silicate glass
(fluoride releasing) and is available in 7 shades: A1, A2, A3, A3.5, A03 (Opaque Dentin), CV (Cervical Shade), and BW (Bleach White).
Common applications:
- Excellent for use as a Liner/Base
- Block out undercuts
- Restore imperfections
- Great for Tunnel Preps
- Sealant – 60 second sealant when used over GC G-Bond™, the one component, one coat, self-etch Bonding Agent

Features & Benefits:
Very Low Viscosity
- High flow characteristics
- Flows easily for use as a liner or base
- Flows quickly to place as a sealant when used with G-BONDTM, the revolutionary one component, one coat, self-etch Bonding Agent
Filled Composite Resin
- Silica filled with average particle sizes of 0.7 micron.
- Radiopaque
- High polishability
Available in 7 Shades
- A1, A2, A3, A3.5, A03 (Opaque Dentin), CV (Cervical Shade), BW (Bleach White)
Fluoride
- Contains fluoro-alumino silicate glass filler which releases fluoride ions improving the resistance of teeth to acidic attack and prevents secondary decay
