film’s notch in the upper right corner as shown. In this orientation, the film will have its prismatic structure facing
up and the grooves running vertically. A clear removable premask will be covering this surface while a colored
removable premask will cover the planar surface.

The following steps are a guideline for incorporating Vikuiti™ TRAF II into your liquid crystal display. Clean room
gloves should be worn during the application process to avoid fingerprints, scratches, and debris.
1. Convert the film to the desired part size. The premask should remain on the film during this stage.
• Die cutting is the recommended form of converting, resulting in the cleanest edges.
• Shear cutting is also an option for converting, but may result in rough edges.
2. Remove colored premask from the planar side of the film.
• Place the film on a clean flat surface.
• Use Scotch® Magic™ Tape #810.
• Apply a piece of tape 1/2" from a corner of the film, leaving a 1/2" tab.
• Using the tape, peel back the premask at approximately 180°.
• Peel the premask toward the opposite corner of the film.
• Discard the premask.
3. Remove the clear premask from the prismatic side of the film using the same steps as in #2.
4. Remove any loose debris from the film by using compressed air.
5. Place the film with the prism structure away from the LCD.
• A pressure sensitive tape (such as Scotch® Double Coated Film Tape #415) may be applied along one edge
or two adjacent corners.
• A pressure sensitive tape may not be necessary if you can capture the film in the frame of the display.
