Covestro Receives First DNV Adjustment Certification for Partial Reduction Factor γm1 of Wind Turbine Blades Using Aging-Resistant PU January 17 2022

2022 Lucintel Composites Market Insights, January 17, 2022

Covestro has now received the first adjustment certification from DNV, the wind power industry's certification organization, for the so-called partial reduction factor γm1 of wind turbine blades made of aging-resistant polyurethane (PU). This factor is an important indicator of the long-term aging resistance of rotor blades and is also used to measure the long-term service performance of the blades. It is also the first time that DNV has evaluated and adjusted this factor.

To do so, DNV evaluated complex and rigorous comparative tests as well as theoretical analysis by Covestro. Based on design standards for wind rotor blades (DNVGL-ST-0376:2015), DNV confirmed and adjusted the partial reduction factor γm1 of polyurethane resin processed using the vacuum infusion process. This certification applies to the Baydur 78BD085 PU resin and the Desmodur 44CP20 hardener from Covestro.
