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.
Product Features
- Excellent acid corrosion resistance
- Low resin demand, allowing high filler loading for low cost
- Excellent mechanical property of the composite parts
- Excellent static control and choppability
- Very fast wet-out (solubility)
