 The PermaGard SAG Series of Superior Anti-Graffiti and window protection films are a family of pressure sensitive adhesive coated, optically clear, overlaminating films that are available in ‘good, better, best’ quality options.
SAG 53 (‘better’ option) is a 2.0 mil hard coated, scratch resistant high gloss and ultra-clear, durable polyester face with excellent graffiti, UV and abrasion resistance. It has an optically clear, acrylic, pressure sensitive adhesive protected by a 78# smooth white kraft release liner. It’s best used as a laminating film.
SAG 53 can be laminated to photographic prints, transparencies, latex, solvent-, eco-solvent, water-based and UV inkjet prints, and UV screen printed images to impart superior protection for your graphics from graffiti, abrasion, UV light degradation, dirt, moisture and many other potentially damaging effects in both indoor and outdoor environments.
SAG 53 can also be used in private or public transport vehicles and
areas (trains, subways, tramways, buses...) that require graffiti and window protection.
SAG 53 also increases the impact resistance of windows. (Note: For safety reasons (emergency exits), it is important to keep some windows unprotected). SAG 53 can be wet applied directly to windows and mirrors or first laminated to a pressure sensitive print media and then applied onto flat surfaces.
SAG 53 has very good solvent resistance, so if tagged, the graffiti can be easily cleaned off using most commercially available graffiti removing cleaners without damaging the graphic.
NOT RECOMMENDED FOR: Application on riveted, embossed or curved surfaces. The edges of the product could be affected in the case of frequent contact with solvents. Mactac recommends edges sealing if this is a concern.

Durability
The durability of the film is up to 2 years outdoors and 5 years indoor. While all PERMACOLOR overlaminating films have UV resistance built in to help extend the life of your image, the durability of the image is mainly dependent upon the quality of the inks (see technical data sheets given by the ink manufacturers) and pressure sensitive media being used.
Shelf Life
Two years when stored at 75°F (24°C) and 50% relative humidity or less. Note: Mactac recommends that
rolls be stored on end or suspended from the core.
Chemical Resistance
Resistant to non-abrasive soaps, denatured alcohol, water, detergents and most diluted acids and alkalis.
It is not affected by short term contact with most of aliphatic and aromatic hydrocarbons, ketones, esters,
chlorinated hydrocarbons and alcohol
Recommendations
• Where exposure to moisture, chemicals, solvents or high pressure wash is anticipated, Mactac recommends sealing the edges with varnish, silicone or other sealant to prevent penetration by these liquids.
• The addition of heat while simultaneous mounting with Thermal Overlaminates may result in curl or have other detrimental effects on the finished product.
• Whenever possible, always test first to ensure end-use capability. |
