622 Fiberglass Assembled Roving for Centrifugal Casting
622 Assembled Roving for Centrifugal Casting process is coated with a silane-based sizing, compatible with unsaturated polyester resins.
622 is produced by using a proprietary sizing formulation and a special manufacturing process, offering very fast wet-out and low resin demand. These features enable maximum filler loading and thus minimum manufacturing cost for pipes. The product is mainly used to make centrifugal casting pipes of various specifications and also in some special spay-up processes.

Storage
In general, fiberglass products should be protected from moisture. The best storage conditions are temperature -10℃～35℃, relative humidity ≤80%. To ensure personnel and product safety, pallets should not be stacked more than three layers high. When stacking of overlapping products is required, move the upper tray correctly and smoothly.
