Wind energy is unstoppable—but only with materials that can keep up. As turbines grow taller, blades stretch longer; capacity and performance demands intensify; Evonik delivers the advanced materials that make it all possible. From lightweight core materials and modified resins to crosslinkers and coupling agents, our solutions are engineered to withstand the toughest conditions in rotor blade construction.
Evonik's high-performance products play a prominent role in the production of durable rotor blades. Our crosslinkers, coupling agents, core materials and modified resins address mechanical strength, fatigue resistance, adhesion and weathering resistance.
Solutions by Application Area
Rotor Blades & Composite Structures
Wind turbine blades must be strong, lightweight, and fatigue resistant. Evonik’s materials ensure optimal performance across the entire blade length.
- VESTAMIN® IPD – State-of-the-art crosslinker for the liquid epoxy matrix technology used in rotor blades. It's also essential for enhancing the performance of the adhesives used, providing reactivity in the curing process and giving the final composite parts outstanding mechanical strength.
- DYNASYLAN® – Coupling agents give a lasting connection between glass fiber mats and resins, helping to optimize the stability of composites. These products improve adhesion, minimize moisture sensitivity and protect glass fibers.
- ROHACRYL® – The acrylic chemistry-based structural foam is a core material solution that has excellent mechanical properties and is thermally stable. It is lightweightand easy to shape.
- ALBIDUR® and NANOPOX® – improve fatigue performance under the harshest of environmental conditions.
Adhesives
Robust adhesives enable the construction of longer rotor blades and ensure greater durability.
- ANCAMIDE® – High-performance curing agents that extend gel times to increase bond line lengths and enable the manufacture of even larger rotor blades meeting future demand and production challenges.
- ALBIDUR®, ALBIPOX® and NANOPOX® – Modified resins enable long-lasting components, whether as tackifiers for fabrics or tougheners for paste adhesives and infusion resins. They improve rotor blade service life by providing exceptional fatigue-resistance properties.
Coatings & Resins
Rotor blade coatings enhance weather resistance and boost durability.
VESTANAT® - Cycloaliphatic polyisocyanates used as gel coats, coatings or in-mold coatings for rotor blades that optimize drying and chemical resistance, improving the rotor blade's resistance to weathering
