Adhesion / Adhesive Strength Neoxum Display Protection

Adhesive forces on surfaces

Neoxum display protection films and our OnScreen ® hybrid glass adhere purely through physical adhesion, meaning the films attach to the display using a kind of “suction cup at the nanometer level” without any use of glues or adhesives. When removing Neoxum display protection films or hybrid glass from the display, no residues remain on the display.

Physical Chemical Forces

Several factors play an important role in the adhesion of high-quality screen protectors to screen surfaces. Adhesion is a decisive phenomenon in the molecular range that arises from polar interactions at interfaces, in our case the interface between the display surface and the silicone adhesive layer of the display protector. In particular, so-called van der Waals bonds in the area of molecules of the display surface and molecules of the adhesion layer (the very thin silicone adhesive layer) are decisively responsible for the strong adhesion to smooth surfaces. The decisive condition of adhesion is the spatial proximity of the two surfaces. The silicone adhesion layer of the Neoxum display protection or surface protection is such that Neoxum display films, as well as the OnScreen Hybrid Glass adhere extremely well to numerous smooth materials, such as plastic, metal, but also glass. The adhesive film and the hybrid glass can be removed from all materials without leaving any residue.

Why is that 

Commercially available simple adhesive films usually have an adhesive layer made of acrylate adhesive or modified acrylate. This adhesive layer exerts much stronger physical bonds than the adhesive forces of the adhesive films. This type of acrylic adhesive film usually CANNOT be removed from displays without leaving residue after a few weeks or months of use.
