Tinted Car Windows

Many automobile owners tint their car windows. There are many practical reasons. Tint film on car windows, can reduce the summer heat inside the car, up to sixty percent. Ninety-nine percent of the sun's ultraviolet rays (UV) is blocked from entering the car: Reducing the chance of getting skin cancer (UV - A, and UV - B), and preventing the ultraviolet rays from damaging the car upholstery, or leather from cracking and fading. During an accident, tinting film helps prevent shattering glass from injuring the driver and occupants. Tinting reduces the glare from the sun and other headlights, securing a safer driver. Tinted film windows provide privacy and inhibits burglar from seeing any contents within a car. 

Tinting is manufactured usually by clear polyester film with a very thin layer of dyes (absorbs the heat), and two processes: Depostion technology (vacuum coating/metalizing), and Sputting technology (advanced metalizing) deposits a layer of metallic particles, that provide a reflecting coating. Layers of film are bonded together. On one side is pressure sensitive or water - activated adhesive. Chemical UV blocker (cyclic imino esters) is added, for purpose of blocking - out the ultraviolet radiation. Some tinted windows contain hybrid film, which combines mounting adhesive, dyed polyester film, laminating adhesive, metalized film and scratch resistant hard - coat. Hybrid film last for five years, and Sputtered or Deposition window film can last for a decade. A reputable tinted window dealer will use quality film and provide a window film warranty for five years or lifetime warranty. The tinted film reflects a percentage of visible light (VLR), absorbs light (VLA), and transmits visible light (VLT), which has the highest percentage. Depending on the quality and type of tinted film that is applied, either VLA or VLT will have a higher percentage. Drivers that have poor vision should have only lighter tinted windows.
