Henkel Corp. says it has introduced a full line of its Loctite adhesives, sealants, lubricants and coatings for installation and maintenance of wind turbine blades, nacelles, towers and bases.
For rotor-blade repair, Loctite polyurethane resins cure rapidly at room temperature, reducing the downtime associated with blade maintenance, Henkel says. Specifically formulated to restore composite blades, the resins are used to patch and repair structural cracks on blade tips and stress risers, impact damage, wear and erosion.
On the nacelle, Loctite operations and maintenance (O&M) products provide UV/moisture resistance to seal against harsh weather conditions. Cleaners and lubricants keep equipment running reliably, high-traction coatings prevent slipping on interior and exterior walkways, and anaerobic products maintain threaded fasteners, joints and flanges, according to Henkel.
Loctite O&M products are designed to seal out moisture and prevent corrosion on tower sections, load support plates, platforms, bolt heads, ladder frames and metal surfaces. The products are also used for ladder bonding and thread-locking.
On the base, Loctite grouts facilitate tower installation and ensure the structure is level and secure, Henkel says, adding that sealants prevent water ingress around electrical cables and concrete repair products correct damage and cracks.
