Direct Roving for Filament Windling 308S

308S Direct Roving or Assembled Roving is produced with E6 glass formulation and
coated with a silane-based sizing composition.It is specially designed for reinforcing
epoxy resin and suitable for both amine and anhydride curing systems.

The composites of epoxy resin reinforced with 308S have excellent mechanical and anti-fatigue properties.308S is suitable for high-tension winding and pultrusion processes.Typical applications include wound pipes,high pressure cylinders and pultruded profiles.
