Description

WV139 is a 6 mil soft white vinyl film with black reverse side and 70% print surface and 30% open area with a 1.4 mm hole diameter for one-way visibility. The product is coated on one side with a removable, clear, acrylic pressure sensitive adhesive and supplied with a 6 mil paper release liner.
WV139 is designed for solvent based, ink jet printing for window graphics viewed from one side and “see-through” from the other side.

External Applications:

Window graphics applied onto flat glass surfaces showing advertising on one side and allowing “see-through” from the other. WV139 can also be used in conjunction with opaque marking films for vehicle and public transportation advertising. Application is not guaranteed when heaters on
rear windows are in operation. The use of rear wipers is also not recommended. To make full use of the advertising, it is recommended the inside lighting of the vehicle to be dimmer than the lighting on the outside of the vehicle, especially at night. WV139 can also be used to reduce heat and glare from the sun inside vehicles and glass buildings. Internal Applications: Because of its one-way visibility, WV139 can be used for surveillance purposes in
shops, department store, stock rooms, etc.

Warning:

Application of vinyl film that renders emergency exit windows inoperative is prohibited under National Traffic and Motor Vehicle Safety Act of 1966 (recodified at Title 49 U.S.C.) The application of vinyl film over the emergency exit window seals will not permit the emergency exits to function as intended. This creates a safety hazard. In order to permit the exits to function, it is necessary to trim properly around the emergency exit seals. Often, the window seals do not coincide with the window frame edge.
If a manufacturer, distributor, dealer or motor vehicle repair business renders an item of safety equipment inoperable, they are subject to civil penalties outlined in 49 U.S.C. § 30165 (a penalty of not more than $5,000 for each violation, maximum penalty under this subsection for a related series of violations is $15,000,000).

Durability
The outdoor durability of the unprinted film is 18 months. However, actual durability of the printed graphic is dependent on the inks and overlaminates used. Some adverse reactions may occur when applying WV139 to certain substrates such as acrylic glass, polycarbonate, polystyrene, plasticized PVC and certain paints. These reactions have a negative effect on the adhesive performance.

Glass Breakage
MACtac accepts no liability for glass breakage due to temperature differences across the glass which can be caused by sunlight on dark areas of the graphic. Size, thickness, quality of cut, edge treatment, tinting and frame design all effect temperature stress.

Shelf Life
1 year from D.O.M. when stored at 60/77°F (15/25°C) and 50% relative humidity in the original package.
