Wind energy is on the rise as a climate friendly source of energy. Ever larger rotor blades are constantly increasing the power output of modern wind turbines. The stresses and strains to which rotor blades of wind turbines are exposed at 90 meters above the ground are truly immense. Reaching top speeds of up to 300 kilometers per hour, forces are exerted on blade tips which make them bend for more than a meter. Weather conditions such as snow, rain, heat and UV radiation also take their toll on the blades. BASF is supporting the manufacturers of these mighty machines by supplying epoxy resin systems for highly resilient, fiber-reinforced components and coatings for rotor blades. The topcoats are matt to prevent the sun being reflected from the rotor blades which could pose a potential hazard for air traffic. The coating systems marketed under the name "Oldodur" consist of several products, such as gelcoat, surfacer, edge protection and topcoat.
