- 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.
Wind power is a core element of the Covestro sustainability concept. Various products and their advantages are therefore combined in Covestro’s wind energy portfolio.
Thinking outside the box – together
Wind energy: Strength and protection for valuable energy assets
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.
