Window film

A tinted film is mainly used in the automotive industry a PET film, which is used for sun protection, but also to darken. The films are to be distinguished from the solar control films, such as those used for windows of houses. Tint films are produced primarily for subsequent sun protection on unprotected car windows. Due to its low light transmission (up to 3%) in some special variants they are also used as a screen.

Construction

A tint film consists of one or more layers of PET film. The film is an adhesive layer, usually consisting of acrylic resin. This adhesive is covered by an additional protective film. Single-layer films pale by solar radiation of relatively quickly and get this purplish up to the utter fading after several years. Multi-layer films, however, are very resistant and scratch resistant. They are hardly this Ausbleichungsprozess. The manufacturers give some long guarantees on the quality of these films.

Processing

The tint film is glued after adjusting and cropping in on the car window. Since the PET films are, they can not simply pull or stretch. By today's more or less curved auto glass a wrinkle or bubble-free installation is difficult. This concerns especially the often highly curved rear windows. The films must be " shrunk " by using hot air at about 240 degrees on the disc shape. This takes a lot of practice and experience, as these PET films at about 250 degree "burn" and then are useless.

Purpose

The film gives the car a different look and granted with the appropriate impermeability a good visual barrier. In addition, it reduces the heating of the interior of a vehicle and is used as a sunscreen. Almost all window tint films absorb the aggressive UV -A and UV -B radiation at about 360 nm to about 99%. These rays mainly contribute to the fading of interior materials and damage the skin of the occupants. Depending on the type and shade of the films, these heat radiation from the sun by up to 60 % back and reduce the heating of the vehicle interior.

Through its splinter protection tinting films provide additional protection against glass splinters in case of an accident dar. Besides the windscreen made of laminated safety glass made ​​the vast majority of car windows still from conventional toughened. Meanwhile splinters can cause injury in an accident. Tinting films can bind glass splinters and reduce the risk of personal injury.

Terms of Use

In Germany, only approved films that have a General Type Approval (ABG ), be placed in vehicles. The ABG- number must be visible on all laid films. The certificate shall be carried and produced on demand. An E-homologation is not necessary. The tinting films may only be applied to the non -relevant for the driver's view panes are so moved the rear side windows and the rear window. A second mirrors is then imperative. On the windshield, only a facing strip may be attached, which covers a total of not more than 25% of the windshield and is not greater than 0.1 m². In addition, the driver's field of vision may not be affected. Even the laying of clear safety films is prohibited on the front side windows or windshield.
