Structural Adhesives for Wind Turbine Applications

Structural adhesives are applicable to a variety of wind turbine structure components including:

Blade assembly
- Blade bonding
- Void filling
- Bolt, stud, and metal-insert fixing
- Panel and stringer structural bonding
Nacelle assembly
Hub, bearing, and gearbox assembly
Electrical component sealing and protection
Magnet bonding and coatings
Tower assembly
Installation, maintenance, and blade repair

Cure Time Critical to Blade Bonding

Curing times are a crucial aspect of bonding. Some applications require adhesives that cure quickly, such as repair operations, while other applications need a slower cure time, as in manufacturing.

Large wind blades, for one, need a slower cure time. When bonding the two blade halves and laying down beads of adhesives, it's good to have a curing process begin at the same time. An adhesive should not start curing before all of it is applied to the entire blade. When the dispensing finishes, the two halves are placed together, and the curing can commence. Curing at room temperature lets the adhesives provide crack resistance for a variety of composite, metal, and plastic assemblies.

Engineering assistance is available for joint design, fixturing recommendations, adhesive selection, and MMD (bulk dispensing) equipment guidance. If you need help choosing one of our standard adhesive products or if they don’t quite meet your needs, let us help you find a solution.
