Description
Blades are constantly exposed to weather, and the taller the wind turbine, the steadier and stronger the wind, so requirements for coatings grow with turbine power. The coating must resist abrasion and erosion and at the same time stay elastic. The manufacturer formulates three requirements. The first is flexibility without cracking under extreme temperature changes and strong blade bending. The second is durability against ultraviolet and erosion from rain, hail and sand, most of all on the leading edge, where the circumferential speed is highest. The third is safe application in various climatic and technical conditions at blade factories. For operation there is the ALEXIT BladeRep repair system, which quickly restores the blade coating. The composition and characteristics of the system are not disclosed in the open data, and details about BladeRep are available at bladerep.com.
How to choose
Two scenarios need to be distinguished here. For painting new blades at the factory the ALEXIT Wind coating is taken, for repair on the turbine the BladeRep system. Site conditions, whether sea or desert, set the abrasion and erosion requirements. For introduction into the customer's processes, theoretical and practical training at application centers is available.

FAQ
What is the ALEXIT BladeRep system for?
For long-term protection and quick restoration of the coating of blades that are constantly exposed to extreme weather.
What does the wind turbine blade coating protect against?
From abrasion and erosion due to rain, hail and sand, from ultraviolet and from cracking when the blade bends.
Why does the leading edge of the blade wear the most?
The circumferential speed is highest there, so erosion from droplets and sand is strongest.
For how many years have the coatings been tested in practice?
More than 20 years, and the blade products are qualified by leading wind turbine manufacturers.
Is there training for applying these coatings?
Yes, theoretical and practical training is held at application centers to fit the products into the customer's processes.
