SAG 38 is a high gloss ultra clear durable polyester film with good UV and abrasion resistance. Thanks to its good solvent resistance, graffiti can be easily wiped clean from SAG 38.

Construction:
Face material:
1.5mil (36 ?m) UV and abrasion resistant PET film.
Adhesive:
Long life clear acrylic pressure-sensitive.
Liner:
1.4mil (36 ?m) clear PET

Typical Uses:
SAG 38 is a lamination film developed to protect private or public transport vehicles and areas (trains, subways, tramways, buses...) that require a graffiti protection. SAG 38 is not directly applied on the vehicles but is first laminated to a pressure sensitive (SAG 29 for decoration with a printed image or MACal 9800 Pro for decoration with a plain color). This combination of films can be applied only onto flat surfaces. Application on riveted, embossed or curved surfaces is not recommended. The edges of the product could be affected in the case of frequent contact with solvents.

Note: SAG 38 increases the impact resistance of windows. For safety reasons (emergency exits), it is important to keep some windows per carriage unprotected.

Durability:2 Years
Note: Exposure to severe temperatures and ultraviolet light, as well as conditions in southern US states and European countries, and in tropical, subtropical or desert regions, will cause a more rapid deterioration. This also applies to polluted areas, high altitude and south-facing exposure.

Chemical resistance: ANSI Z26.1 test #14 (non-stressed).
Resistant to non-abrasive soaps, denatured alcohol, water, detergents and most diluted acids and alkalis. Not affected by short term contact with most of aliphatic and aromatic hydrocarbons, ketones, esters, chlorinated hydrocarbons and alcohol.

Processing
Lamination
Mactac recommends to laminate SAG 38 on the vinyl film (SAG 29 or MACal 9800 Pro) with a professional laminator.
Application
To be done on a clean and degreased substrate with the dry application method.
Maintenance and cleaning
The cleaning solution must be wet, non-abrasive, without strong solvents and have a pH value between 3 and 11.
Product removal
Removal of SAG 38 and vinyl laminate will be made easier using heat. The remaining adhesive residue can be removed using isopropyl alcohol. Note: more adhesive residue will remain on surfaces using nitro-cellulosic paints and abraded paints. Removability is not warranted where varnishes or paints have not been fully oven dried or have insufficient anchorage to the substrate (i.e. due to the presence of rust, chipped paint...). We recommend removing the film at an angle of 90°, slowly and at a constant speed. Any adhesive residue can be removed with isopropyl alcohol.
