The adhesive system plays a critical role in the long-term durability of an Aluminum Honeycomb Panel.
Common adhesive types include:
- Two-component polyurethane (PU)
- Epoxy structural adhesive
- Modified epoxy adhesive
- High-temperature adhesive
- Marine-grade adhesive
A high-quality adhesive should provide:
- Excellent peel strength
- High shear strength
- Weather resistance
- Moisture resistance
- UV stability
- Thermal aging resistance
Poor adhesive performance is one of the leading causes of panel delamination, especially in regions with high humidity or extreme temperature fluctuations.
Buyers should request bonding strength test reports and accelerated aging data rather than relying solely on the adhesive brand name.
