Capa wind power

Capa™ 4101 is a unique polyester polyol, with excellent chemical resistance and outstanding durability, making it possible to survive the toughest conditions. This makes Capa™ 4101 perfect in coatings for airplanes, wind turbines and automotive industries. All of this is possible due to functionality 4.0. 

Some of the largest wind turbines are more than 120 meters high with blades up to 60-80 meters long. A wind turbine can reach a cut-out wind speed up to 20-25 m/s, in windy conditions and a typical operating temperature within a range of −30 to 40 °C. Add rain, snow, hail and chemicals in the air and it’s not difficult to imagine that the tip of the blades, are being put through extreme conditions. Dismantling and repainting a wind turbine is extremely expensive and time consuming. If you can prolong the time between service intervals, you can therefore save a fair amount of costs and time. 
 

Surviving tough conditions with functionality 4.0

Capa™ 4101 is the ultimate polyol for industrial coatings, which need to last in the toughest conditions. Even in the coldest weather conditions, Capa™ 4101 ensures that the coating remains flexible, scratch resistant and resistant to impact. This makes Capa™ 4101 perfect in coatings for airplanes, windmills and automotive industries, as illustrated in the example above. For customers this means, that service intervals can be prolonged, which saves maintenance cost and downtime. 

The techie inside

As mentioned, Capa™ 4101, can survive very tough conditions due to its 4.0 functionality, a combination of four reactive groups and a balanced equivalent weight, enables a dense but tough network. This gives an extremely durable product with excellent chemical resistance. On top of this, it is a liquid low viscosity and solvent free polyol, which can help reduce the VOC level of the final coating and adds additional sustainability benefits. For most coatings it’s impossible to combine these four properties. However, with CapaTM 4101, this is no longer the case. Moreover, the four properties, illustrate the main benefits CapaTM 4101 brings to the coating.
