Processing Guidelines
- Melting Temperature: 200°C - 240°C
- Application Methods: Hot melt extrusion, bead dispensing, slot die coating
- Open Time: Adjustable depending on granule formulation, typically 30-180 seconds
- Substrate Prep: Clean, dry surfaces; light abrasion or plasma treatment can enhance bond strength
Wind Turbine Blade Applications
- Bonding of internal spars or shear webs to shell sections
- Adhesive joints between blade halves (leading and trailing edges)
- Fixation of foam or core inserts
- Repair of delaminated or cracked structural zones
- Integration of root bushings or metal inserts
Key Advantages
- High Temperature Resistance
- Strong Mechanical Bonding
- Fatigue Resistance
- Low Shrinkage
Frequently Asked Questions
Why use PES hot melt granules instead of epoxy adhesives?
PES offers faster processing, less curing time, and thermoplastic flexibility, enabling quicker production cycles and easier rework or repairs compared to traditional two-component epoxies.
Are PES adhesives compatible with composite materials used in blades?
Yes, PES bonds well with composite substrates including fiberglass, carbon fiber, epoxy prepregs, and foam cores.
