Wind Turbines
For both onshore and offshore wind turbines, we offer effective corrosion protection and elastic sealants. Our solutions safeguard components from harsh weather conditions, minimize material fatigue, and extend service life. With innovative coatings and sealants, we help reduce maintenance costs and ensure reliable energy production-maximizing both efficiency and cost-effectiveness.
Corrosion Protection
Corrosion protection is crucial for wind turbines to ensure their longevity and reliable performance, both onshore and offshore. Exposure to harsh weather, salty air, and moisture can severely impact metal components, leading to costly damage and reduced efficiency.
DINITROL offers highly effective corrosion protection solutions specifically designed for wind turbines. From robust protective coatings to flexible sealants, DINITROL products safeguard tower surfaces, bolted connections, and circuit boards against environmental influences. Thanks to innovative formulations, these solutions are easy to apply and seamlessly integrate into maintenance routines, supporting sustainable and economical energy production by extending service life and reducing maintenance costs.
Our solutions
Cavity Protection
Wind turbines are exposed to extreme weather conditions and require the best possible protection for long-term, reliable operation. This is especially important offshore, where salty sea air accelerates corrosion and steel structures are particularly prone to rust. To maintain the stability and efficiency of wind turbines, effective cavity protection is essential.
DINITROL 4010 provides a highly effective solution for cavity protection in wind turbines. This durable corrosion protection agent is easy to apply inside turbine cavities and forms a resilient protective layer once dry. DINITROL 4010 offers outstanding protection against rust and external influences, even under the toughest conditions. The product is extremely versatile, delivering long-lasting corrosion protection and high mechanical resistance thanks to its strong adhesion and high temperature tolerance. By applying DINITROL 4010 in cavities, even hard-to-reach areas are optimally protected. The product penetrates deeply and acts like a cavity wax, supporting the safe, long-term operation of wind turbines and guarding against unwanted corrosion.
Our solution
Surface Protection
Wind turbines are exposed to extreme weather conditions around the clock. Rain, wind, UV radiation, and salty air constantly attack their surfaces, leading to corrosion, material fatigue, and mechanical wear. Effective surface protection is therefore essential to extend the lifespan of towers, rotor blades, and other components while avoiding high maintenance costs.
DINITROL offers powerful solutions for corrosion protection in wind turbines. The rust converter DINITROL RC 900 penetrates deeply into the material, transforming rust into a stable protective layer. After curing, a zinc primer (DINITROL 443 or 444) can be applied, followed by DINITROL 445 -a paintable stone chip protection based on resin and plastic. This combination provides reliable protection against mechanical stress, saltwater, and aggressive cleaners.
With the right protective coatings and regular maintenance, downtime can be reduced, repair costs minimized, and the long-term efficiency of the system ensured.
Our solutions
Screw Connections (Internal & External)
Screw connections are a crucial part of wind turbines, ensuring the structural integrity of the entire system. Both internal and external screw connections are vulnerable to corrosion damage. Moisture, salty air, and environmental factors promote rust formation, which can lead to wear and malfunctions. Proper corrosion protection is therefore essential to prevent costly repairs and ensure the longevity of the systems. During maintenance and upkeep of wind turbines, targeted application of corrosion protection agents on screw connections is recommended.
For bolts inside the turbine, a two-layer system of DINITROL ML and DINITROL 4941 provides a long-lasting protective barrier.
For external screw connections, DINITROL RC 900, a powerful rust converter, is used in combination with DINITROL 445. A final coating creates a durable and resilient protective layer.
This targeted corrosion protection not only minimizes wear on screw connections but also extends the overall lifespan of the wind turbine. Regular maintenance with DINITROL prevents rust, reduces downtime, and lowers maintenance costs over the long term.
Our solutions
Corrosion Protection for Service Cranes
Service cranes located in the turbine housings of wind turbines are exposed to harsh weather conditions that can lead to corrosion and wear.
DINITROL 3850 creates a durable, wax-like protective film with excellent abrasion resistance, delivering long-lasting corrosion protection for the interior of the cranes. Thanks to its low dry film thickness, it provides efficient coverage and extends maintenance intervals to as much as 4–5 years.
Our solution
Circuit Boards
Circuit boards are essential components in wind turbines and must be protected against harmful environmental influences. Corrosion can severely impair their functionality and cause failures.
DINITROL corrosion protection products offer reliable, long-term solutions for safeguarding circuit boards. Special coatings form a durable barrier that extends the lifespan of electronic components and significantly increases their resistance to corrosion.
Sealants
Sealants play a crucial role in maintaining wind turbines, ensuring their efficiency and longevity over the long term. They reliably protect sensitive areas-especially electrical connections-from moisture, dirt, and other environmental factors.
DINITROL sealants are specifically used during maintenance to safeguard functionality and prevent damage from external influences. This targeted protection significantly maximizes operating times and helps minimizing maintenance costs.
Our solution
Sealing Maintenance Joints
Sealing maintenance joints is essential in wind turbine upkeep to prevent the ingress of moisture, dirt, and other environmental factors. Using high-quality sealants ensures these joints are reliably protected, safeguarding sensitive components and electrical connections from corrosion and damage. This practice increases the operational safety of the wind turbine, reduces downtime, and extends the overall lifespan of the system.
DINITROL 425 UV is a universally applicable adhesive and sealant with excellent stability, outstanding UV stability, and high weather resistance – ideal for applications in both indoor and outdoor areas. Thanks to its user-friendly handling, reduced preparation times, and high-quality finish, it impresses both in processing and in the result. The perfect solution for efficient work with professional standards.
DINITROL 770 is a moisture-curing, one-component silane polymer with excellent weather and UV resistance. The sealant and adhesive offer excellent adhesion to glass, metal, wood, plastics (except PE, PP, PTFE), and many other surfaces. It is solvent- and isocyanate-free, prevents bubble formation, and ensures a clean, durable result. Ideal for outdoor and indoor applications under challenging conditions.
