BASF has unveiled its RELEST Wind LEP paint designed to help protect the edges of wind turbine rotor blades. The company claims tests show the new polyurethane coating offers four times higher resistance than conventional solutions.
As BASF explains, wind turbine rotor blades are exposed to enormous stresses, including rain, hail, snow, sand and UV radiation. At the blade tips, speeds can reach up to 300 km per hour.
BASF's Harald Muller says the product can fit customers' individual needs. "Rotor blade coating is performed in a variety of ways depending on the manufacturer – for instance, by hand with brushes, rollers or spray painting. The paint can be used with all of these methods." In addition, the company says the product can be applied under a wide range of climate conditions.
