- SURFITEX™ BENEFITS INCLUDE
- High-quality surface finish
- Improved esthetics and surface smoothness
- Reduced reinforcement print-through
- Elimination of surface penetration of reinforcement fibers
- Superior corrosion resistance
- Enhanced abrasion resistance
- Improved resistance to UV discolouration and degradation
- Reduced die-wear, lowering pulling forces and increased line speeds
- Mouldability to complex shapes
- Fast wet-out increases processing speed
- Elimination of micro-cracks
- Advantages
Surfitex™ gives FRP components a resin-rich surface that enhances weathering and corrosion resistence and reduces UV degradation. It also provides a smooth, crack and craze-resistant finish, minimizing reinforcement print-through.
Surfitex™ are hydro-entangled polyester surface veils for FRP, with advantages over standard C or ECR glass veils/tissues.
These advantages include:
• Improved corrosion resistance
• Improved UV andweathering resistance
• Binder-free (hydro-entangled – no risk of chemical contamination of the resin)
• Compatible with all resin types
• Easy resin wet-out and infusion
• Retains tensile strength when wet
• Improved aestheticsand smoother surface for pultrusions
• Cost-effective solution
