The innovative Aerobond system from Henkel significantly speeds up laminating processes in the paper and woodworking industry while improving their efficiency at the same time.

Together with the Hansa Mixer company from Bremen, Henkel has developed a system solution for the aeration of laminating adhesives that enables clean machining even at high production speeds.

The Aerobond system incorporates a laminating adhesive and the Glue-Mix unit from Hansa, a device designed to match the specially developed Henkel adhesive, which introduces controlled quantities of air into the adhesive and distributes it optimally over the substrate surface. This application considerably increases the volume of the adhesive, so that significantly less adhesive is used for the same laminating area.

SIGNIFICANT
The system also has a substantial impact on conditioning times. Conventional adhesive blends typically have high-moisture content, requiring conditioning times of up to 24 hours, which can slow down entire production lines.

With Aerobond, the volume of air in the mix reduces the moisture content significantly, cutting lengthy conditioning times to just a few hours while ensuring better bonding.

The process decreases the moisture content over the bonding area, thus improving flatness. The aerated adhesive is better able to compensate for unevenness across the substrate surface. This improves the initial bond strength and minimises areas with insufficient adhesion.

The Aerobond system is easy to use, offers greater flexibility in production processes, reduces downtimes for cleaning of laminating lines, and allows in-line production.
