...ion of PU for rotor blades is advancing particularly rapidly in China (Fig. 3). A PU resin system is used for this purpose, for instance, based on the isocyanate components Baydur 78BD085 and Desmodur 44CP20 from Covestro, which have certifications including a DNV-GL certification (Det Norske Veritas – Germanischer Lloyd). This industrial standard for the safety, reliability and performance capability of wind energy systems is a key global criterion for using such resins in rotor blades. Exchang...

For the sealing of roof openings, e. g. the roof gully (which, by the way, may often be made of PU integral foams such as Baydur from Bayer), an in-situ foam system can be used, which seamlessly encloses the "foreign body".
