SELF-ADHESICE PROJECTION MIRROR TONKS

      
• The application of the foil takes place the same way as other customary foiling processes for plates of glass, i.e. with a spray of “slip solution” and a rubber squeegee.
      
• Before foiling, please consult your glass supplier first to determine if the plate of glass is suitable for foiling (e.g. thickness, surface coating, etc.).
      
• Please note that the tensile forces that develop between the foil and the glass can be quite strong. There is a danger the glass may break when removing the foil, particularly if the foil covers the entire plate of glass. To avoid this      
              
  • Make scores in the foil beforehand so that it can be pulled off in strips approximately 10 cm wide. (Be careful not to damage the plate of glass itself!)
              
  • Pull the resulting foil sections off the plate of glass at an acute angle.
              
  • If the glass begins to bulge when pulling off the foil, stop pulling immediately and make further scores in the foil so that it can be pulled off in smaller strips.
        
        
      
• Plates of glass plates may exhibit internal tension from previous damage and may burst even when only exposed to light pressure. Therefore, always be sure to wear the appropriate protective equipment (e.g. helmet, goggles, gloves).
      
•  TÜCHLER assumes no liability for the damage or destruction of the plate of glass.

Valid from January 1, 2014

1. Creases
Projection films are generally packed and shipped folded. After opening and stretching the projection films evenly on all sides, the creases usually disappear completely. As far as technically possible, projection films can also be shipped rolled – at an additional cost for packaging and transport. This increases the likelihood of crease-free or complete crease recovery. The recovery process depends on room temperature, tension during installation, and time. Any visible remaining creases do not constitute a reduction in the value of the projection film.

2. Proper use of projection films
Projection films are optimized for front or rear projection depending on the type, for use with the usual angles of light incidence in video, slide, or film projections. A smooth and flat surface is only achieved by evenly tensioning the projection films on all sides. When used under strip or side lighting, uniform tension on all sides is essential. Any visible remaining creases, seams, or waves caused by tension or installation do not reduce the value of the projection film.

3. Evaluation of color deviations and brightness differences
Projection films are manufactured in large-scale facilities of the PVC industry and are subject to strict quality controls. However, even this industry has tolerances. These are very small and often cannot be noticed under normal lighting conditions. Rarely, these deviations become visible under certain application conditions. Please note that color deviations, which only become visible when the viewing angle corresponding to half the luminance is exceeded, are technically inherent and do not reduce the value of the film.

4. Use in roller screens
All projection films can be made by Tüchler® in roller screens in Superflat versions. Please request a quotation. The installation of projection films by third parties in roller screens is done at their own risk. Tüchler® is free of any liability and/or claims for damages in this regard.

5. Dimensional stability + tolerances for cut material
Projection films are made of a thermoplastic material. The material changes its stretch behavior, softness, and length with changes in room temperature. Therefore, cuts are always subject to a tolerance of +- 5% at a room temperature of 22°C.

6. Use in winter and cold regions
Please note that projection films can cool down significantly during transport. In such cases, projection films must be stored and warmed before opening in such a way that the core temperature inside the film package reaches >= 21°C. If the film is opened at a core temperature lower than 21°C, it will be stiff and may suffer cuts or irreversible impressions and white marks from moderately sharp edges. A too low core temperature before unfolding also causes persistent creases.

7. Lifespan of projection films
With proper use and storage at room temperature, your projection film can last for many years. Projection films contain plasticizers that gradually evaporate over time. After several years, this may cause effects such as color changes, yellowing, brittleness, or oily spots on the surface. These effects are not warranty-relevant defects but are normal material-related signs of aging.

8. Exclusion of DIN and other projection standards
The projection film has been optimized for use in theaters, operas, events, exhibitions, tours, and similar applications, and is characterized by its specific color, projection behavior, robustness, and fire resistance. The film was not developed for use in cinemas or similar environments. Any assessment according to applicable standards for projection surfaces, particularly DIN standards, and complaints based on them are excluded unless contractually agreed in writing on a case-by-case basis.
