3M Touch Systems applies a top coat to each ClearTek II touch sensor that fills in the relatively rough surface of the glass substrate. This top coat reduces the surface energy of the touch surface which reduces the likelihood of sharp objects scratching the ClearTek hard coat and the ITO conductive coating. Also, the lower surface energy makes the surface easier to clean, minimizes contaminants adhering to the surface and liquids tend to bead up and flow easier off the screen.
