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!

Key benefits

  • Long-term results: our coatings and cast systems provide excellent performance that lasts.
  • Greater productivity: faster-curing surfaces, fewer coats, and minimal downtime.
  • Customizable: castable PU systems make it easy to customize offshore parts.
  • Minimal upkeep: less maintenance required offshore.

More efficient wind blade production through material innovation

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.

Thinking outside the box – together

At Covestro we collaborate closely with industrial partners and research institutions around the world to pave the way for technological innovations in wind turbines. Our aim is to explore new horizons in wind energy hand in hand with our partners.

Our partners can take advantage of multiple wind energy solutions from wind blades to erosion and corrosion protection.

Wind energy: Strength and protection for valuable energy assets

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.

Anti-corrosion coatings: Faster processing of wind tower topcoats thanks to Pasquick®

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.

Cable protection: PU elastomers keep power projects energized

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.

Wind blade production: High-performance PU infusion resin systems for large blades

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.
