Enhance Wind Turbine Blade Lifespan with Leading Edge Protection

2. Leading edge protection by shells

Advantages of Covestro polyurethane elastomer for LEP shells:

• Flexible polyurethane to facilitate the installation at the leading edge
• Durability against erosion, drop impact and UV
• Good thermal stability

Most common products:

• Desmodur® Elastomer shells

3. Leading edge protection using films

Advantages of Covestro adhesive films for soft shell fixation for windblades:

• Combination of thermoplastic processing with characteristics of a crosslinkable PU adhesive
• Adhesive film is non-sensitive to atmospheric moisture
• Storage and transport capabilities: Non-blocking / non-tacky at room temperature
• Excellent adhesion to various substrates

Advantages of Covestro surface protection films:

• Outstanding abrasion resistance to protect leading edge of wind turbine blades
• Exhibits excellent impact and high temperature resistance
• Color matching of the film product
• Tailor-made-film to create the best solution for our customer

Most common products:

• Bayfol® LR adhesive film for shell fixation
• Dureflex® /Platilon® aliphatic TPU films

4. Leading edge protection using Thermoplastic Polyurethane (TPU)

Advantages of Covestro TPU for wind blades:

• Flexible TPU material for easy installations
• Durability against drop impact, UV and erosion.
• No solvents due to thermoplastic
• Processing (recyleability) , means no VOC
• Long lasting TPU solution means less maintenance and lower costs

Most common products:

• Desmopan® UP line for ultimate protection
