Direct Roving for Filament Windling 308H

308H direct roving is produced with the 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.

308H sizing composition gives strong resin-to-glass bonding,which results in excellent mechanical and anti-fatigue properties of the end composites. The product

is designed for the high tension winding process.Typical applications include small bore sucker rods,high pressure pipes,storage tanks and pressure vessels.
