Structural Adhesives for Wind Energy Contact Us
Wind Turbine Assembly Adhesives
With more than 40 years experience in developing and manufacturing structural adhesives, our extensive line of acrylic, epoxy and urethane adhesives improve wind turbine component strength, durability and appearance, while offering design flexibility, total cost savings, corrosion resistance, and the ability to join dissimilar materials. Compared to traditional fastening methods such as rivets, welds and tapes, LORD Structural Adhesives eliminate the costs associated with metal preparation and finishing operations and are formulated to offer a wide range of open times and cure speeds to improve manufacturing processes and final products. Curing at room temperature, our adhesives are suitable for a variety of composite, metal and plastic assemblies, and are readily available in convenience cartridge packaging to bulk packaging that includes gallons, pails, drums and totes for high volume applications.
Structural Adhesives - Wind 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 achieve an appropriate solution.
