Materials like PU infusion resin systems and coatings to protect towers and blades can help the wind energy sector thrive by enabling reduced production costs, maximal longevity and durable protection. Partnering with customers across the wind energy value chain, we offer materials that can inspire not only innovations in wind turbine design but also help maximize efficiency for wind parks on a larger scale. Partner with us so we can energize wind innovation together!

Wind power is most certainly one of the most sustainable technologies for generating electricity, and there are good reasons why wind energy is growing rapidly worldwide. Wind parks and offshore wind farms are searching for efficient, profitable solutions to increase renewable wind energy to even higher levels.

Covestro is striving to lower the production costs of renewable energy, tackling the risk of fuel poverty, and helping to achieve global climate goals. Through innovative raw materials in numerous wind turbine components, we are helping wind blade and turbine producers to better exploit the power of wind energy for the benefit of society as a whole.

Our polymers portfolio contains numerous solutions for wind farms, like long-lasting coatings for wind towers and blades, durable cast PU systems for cable protection, and high-performance PU infusion resin systems for the production of large wind blades.

When it comes to the curing mechanism for the final coat on giant wind towers, our Pasquick® technology has already enabled a considerable productivity boost during the finishing process. A Pasquick®-based topcoat can be applied after a primer for an effective two-coat process. Fewer coats and faster curing mean more productivity for painting operations. The technology also has a low VOC content for greater resource efficiency all around.

We provide cast PU systems based on Desmodur® and Baytec® to protect and reinforce subsea energy cables in the offshore renewable energy. Our cast PU elastomers can be used in a variety of solutions, from strategically placed bend stiffeners to bend restrictors and more. Desmodur® offers significant protection against impact, bending fatigue and hydrolysisfor maximal longevity with minimal maintenance. Cast PU systems are also easy to customize for rapid, cost-effective installation with fewer risks in personal safety.

Our high-performance polyurethane infusion resin systems are well-suited to the vacuum infusion production of large wind turbine blades. PU resins make lighter, longer and stronger blades possible – and offer several distinct advantages. Thanks to their low viscosity and faster curing and infusion speeds, manufacturers can improve productivity and lower their investment. In addition, PU resins bond far more effectively to glass fibers than epoxy. The result is superior performance, both in terms of mechanical strength and resistance to fatigue.
