VISAR 02 AR Polyester Film
VISAR 02 AR film is a convenient method of reducing the reflectance of flat surfaces.
It consists of a hard coated 100 micron thick polyester film over coated with an antistatic layer on top of which is the antireflective coating. The AR surface has a removable film which gives protection during the application process. There is an acrylic PSA (pressure sensitive adhesive) on the rear of the product with its own release liner.
VISAR 02 AR Film is available both in roll form (up to 1.25 meters wide), or in cut to size sheets.
