Materials


One of 3M Touch Systems core capabilities are the coatings used to create MicroTouch ClearTek II touch sensors. These coatings provide surface durability, anti-glare optics, and scratch resistance.

The 3M MicroTouch ClearTek hard coat was formulated by 3M Touch Systems chemical engineers and is chemically bonded to the touch sensor's glass substrate to provide premium protection of the scratch-prone ITO conductive coating. The ClearTek coat also provides anti-glare characteristics and enhances the light transmission value to 91.5%.

Product implementations:

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.

Product implementations:

3M's expertise in adhesive chemistry has created a conductive adhesive tail bond unmatched in the industry, which completely removes the need for traditional soldering and provides a robust electrical/mechanical connection.

Product implementations:

3M Vikuiti™ light enhancement films are a global standard in the LCD industry and 3M Touch System uses Vikuiti™ advanced light control films (ALCF) to provide customers with a "viewer privacy" option for their touch applications. By laminating Vikuiti™ ALCF to the back of a ClearTek II sensor or between the layers of a ToughTouch II sensor, customers can help prevent non-users to see critical or confidential information displayed on the screen.
