Polyester Surfacing Veils Description
Polyester surfacing veil is a non-woven material made from 100% polyester fiber, held together by a binder through a spunlaced process. It enhances the surface of composite laminates, providing reinforcement and a smooth, resin-rich, durable finish. This unique production and resin permeability treatment give it desirable characteristics, such as a smooth surface, uniform fiber dispersion, soft hand feel, good air permeability, and fast resin penetration, making it suitable for various industrial applications like pipes, containers, tanks, profiles, and general pultrusion and filament winding.

Polyester Surfacing Veils Applications
Polyester surfacing veils, crafted from 100% polyester fiber via special non-woven techniques like spunlaced or needle-punched methods, are used in various composite manufacturing processes such as hand lay-up, pultrusion, and filament winding. They are widely applied in different fields. In construction, they enhance the appearance and weather resistance of building facades and roofing materials. In transportation, they are used for automotive body parts to achieve a smooth finish and in marine applications to prevent water penetration. In industrial equipment, they are used to make tanks and pipes more corrosion resistant and easier to clean.
