PE-Aluminum Adhesive Choices with DuPont™ Bynel®
PE-aluminum adhesive performance is one of the most important requirements for aluminum composite building panels to remain attractive and trouble-free after installation. Because delaminations can be a particularly unsightly and costly repair issue, panel manufacturers must take great care to assure long-term adhesion between the panel core material and outer metal layers.
PE Aluminum Adhesive Placement Alternatives
DuPont offers several specially developed grades of Bynel® adhesive resin for use in laminating building panels. Bynel® resins have been proven effective in a variety of adhesive placement methods (prior to or simultaneous with the aluminum lamination step):
- Coextrusion with the polymer core;
- Lamination with a pre-made film of Bynel®
- Extrusion coating onto the polymer core layer.
