VITO Erosion / Surface Protection Film
Polyurethane film protects rotor blades against erosion
The rotor blades of wind power stations are permanently exposed to heavy loads as, for example, by driving rain with a relative speed about 250 km/h, hail, insects, and dust particles. If the rotor blades are not protected, these mechanical impacts damage the surface in the course of time. Optimal protection against wear, erosion and abrasion can be achieved by applying a transparent polyurethane film stabilized against ultraviolet radiation.
The VITO erosion-protection film is coated on one side with a high-grade acrylic adhesive. It features an excellent resistance to abrasion and can be applied on three-dimensional surfaces due to its superior formability.
Product benefits
VITO erosion-protection films extend the service life of rotor blades without influencing their aerodynamics
