GF 242 Optically Clear Cast Overlaminating Film is a pressure sensitive vinyl with an optically clear permanent solvent pressure sensitive adhesive on a smooth frosted polyester liner. This glossy flexible vinyl affords protection to graphics from ultra violet radiation, moisture and abrasion. GF 242 is recommended as an overlay on GF 232, GF 260, GF 261, GF 270, and GF 280 perforated window films. GF 242 also works well for many other applications where a high-gloss finish is required. Cold laminating techniques are recommended when applying this film.
