Sika is looking back at more than 30 years of successful experience in supplying the renewable energy industry.

As a global leader in specialty chemicals and materials, Sika stands at the forefront of supporting the wind energy industry through innovative solutions tailored for both the manufacturing and repair sectors of wind turbine blades. With a commitment to sustainability and excellence, Sika has emerged as a trusted partner, providing cutting-edge products and expertise to enhance the efficiency, durability, and reliability of wind turbines worldwide.

In the manufacturing realm, Sika offers a comprehensive range of advanced materials specifically engineered for the production of wind turbine blades. These solutions include high-performance adhesives, sealants, and composite resins designed to optimize blade construction processes, improve structural integrity, and enhance overall performance.

Furthermore, in the repair business, Sika provides specialized products and systems for the maintenance and refurbishment of wind turbine blades, nacelles and towers. With a focus on efficiency and longevity, Sika's repair solutions address common issues such as leading edge erosion, structural damages, and surface defects, helping to extend the operational lifespan of turbines and reduce downtime.

Sika provides solutions which meet the highest standards in order to execute a clean and neat repair work in a fast and easy way.

We develop our products for the wind market with the particular requirements of building, erecting and repairing wind turbines in mind to ensure unmatched ease of use and performance.

Using products designed for field repair allows technicians to get the job done quickly and efficiently enabling the turbine to get back online in the shortest possible time.

Sika's technical experts have proven that our service and product solutions enabled original equipment manufacturers and build-to-print partners of wind blades to make their products more durable and lighter.

Sika adhesives have been used to successfully bond thousands of wind turbine blades. Our products offer high strength and crack resistance, ideal for long lasting joints.

Beyond blade bonding, in blade manufacturing many internal and external elements require a wide range of different bonding properties such as adhesion to various substrates, sufficient working time, fast curing and required mechanical level. Sika as manufacturer of multiple different adhesive chemistries has a solution for all.

Sika's structural composite resins allow you to repair major defects and bring back surfaces to their original quality. Repairs can be finalized quickly and thus minimize downtime significantly.

Sika's highly toughened structural adhesives increase safety and prolong service life. Thanks to their fast-curing properties they can lower downtime significantly and therefore reduce levelized costs of energy.

The Sika product range has a proven track record in all kinds of adhesive bonding and sealing applications in multiple industries. They are based on Sika’s own Silane Terminated Polymer (STP) Technology, which combines the high flexibility and durability of polyurethanes with sustainability and easy processing.

Whether the requirement is for a load-carrying bond, or generic sealing, Sika offers a wide range of silicone solutions catering to demanding market requirements. Repair companies that service wind turbines blades and nacelles trust Sika’s technologies for bonding and sealing damaged structures, thereby achieving highly durable joints, and in turn, maximizing turbine lifetime.

After major blade repairs or blade replacement due to extreme damage it is necessary to re-balance the rotor onsite. Sika expands its proven track record in balancing material for factory use by offering products suitably adapted to facilitate easier in-field application.

The adoption of robotic solutions for wind turbine blade maintenance represents a significant leap forward in the O&M market for the wind industry.

As the world strives to maintain the condition and clean energy output of its vastly expanding wind energy infrastructure, Sika and its technology partners are committed to improving automated wind turbine maintenance for the benefit of workers, O&M customers and the transition to sustainable energy systems.

Sika offers innovative, cost effective systems for the construction of high quality plugs and molds. The wide range of epoxy resins and gelcoats with a large span of thermal performance are suitable for the production of composite molds of various size.

Epoxy and polyurethane 2-component adhesives are used in structural bonding of both RIM and prepreg manufactured blades. These high performance products for blade bonding as well as injection and repair have excellent fatigue behavior and crack resistance, optimized rheology, and are fast curing despite offering a long open time.

Vortex Generators improve the aerodyamic performance of the blades by manipulating the air flow. Cable clips keep the lightening systems in place and web locators enable a correct positioning of the shear webs during manufacturing. Rapid fixing and bonding of auxiliary parts and add-ons is a Sika core competence.

The Sika product range of sealants offer excellent weather resistance and long-term protection against damages caused by the various harsh weather conditions alongside your turbine blades.

A consistent weight distribution on the wind turbine is crucial for its full performance and longterm functionality. Sika's high density solutions enable a quick weight balancing at reduced consumed volume.
