A New Adhesive System of Hollow Glass Microspheres

2023-03-09 16:31:55 217
The adhesive system is an innovation in the area of large format graphic films. In this system, approximately 50 µm strong films are equipped. In addition to the adhesive, millions of microscopic (40 up to 50 µm diameter) hollow glass microspheres are utilized in an exact, regular arrangement.

This is achieved through the preceding microstructuring of the surface. The small hollow glass microspheres create a gliding effect between the adhesive and the area to be adhered, enabling precise alignment of the foil.

The hollow glass microspheres sink into the adhesive layer upon application of stronger pressure, and can then be permanently fixed to the base. This technology enables large formatting foils to be adhered.
