Multi-Layered Film reflects only a very small range of infrared rays and uses an infrared absorbing coating this disadvantages.
Multi Layered Film has a very weak tackiness of the dye hard coat of the film and shows that the dye layer easily peels off even with a simple masking tape test. Multi Film has low durability and Layered accelerated weathering.
Multi Film film has low durability and Layered accelerated weathering test in bad weather conditions (using xenon arc)
Weathering (UV) acceleration test (using QUV machine) Relative Magnetic Bearing (radiotelegraphy)
Multi-Layered Films are very easily peeled off in thin layers due to inherent weaknesses of multilayer coatings.
