Car window tinting film comes in several different types.  You’ll want to pick the one that meets your needs and that is compatible with your vehicle. Window tinting film begins as a polyester base two to seven millimeters thick.  The high quality the film, the more of these bases are bonded together.  One side of the film has either water activated or pressure sensitive adhesive and the other side is treated with a scratch resistant coating and chemical UV blockers.  This is how window film begins. But most people don’t want to block just the UV rays, they want some glare protection.  This is achieved by dying the film.  Dye absorbs the heat of the sun and keeps the car cooler inside.  Most films are applied to the inside of the windows; you would not think that the heat could disperse but as the glass absorbs the heat it’s drawn away by outside air movement.  Double glazed windows that have a layer of air between them should never use interior-dyed films so check with your tint shop before choosing that type of film. Then there is reflective car window tinting film, popular because it affords privacy as well as protection.  Metallic particles are deposited on the film using and a second layer protects the coating.  Metallized films reflect heat before it can be absorbed by the glass.  This coated is achieved by two different methods – deposition or sputtering technology. Deposition technology involves passed the film through a bath that contains aluminum, copper or nickel and chrome ingots.  By reducing the pressure in the tank, a vacuum is created.  This aids in depositing metal particles from the heated ingots onto the film when argon gas is introduced into the tank.  The more slowly the film is moving, the more metal is deposited on the film.  This is a fairly cheap process but because the metal particles are large and the film must be thick, this type of film is darker and more mirrored than other types. Sputtering also uses a vacuum chamber but it uses more advanced technology than the deposition method.  Electromagnetic fields are used to bombard the film with ions from argon gas.  This causes the metals present to scatter evenly across the film.  Up to 30 different metals can be used in this process and the film can be much lighter than in deposition technology.  The layer of metallic coating can be less than the thickness of a human hair!  Sputtering allows the manufacturer to manipulate colors, heat absorption and reflectivity.  As you can imagine, films made with sputtering technology are on the higher end of the price scale in the car window tinting film industry. Hybrid film contains both reflective metals and dyes.  This process lessens the impact of both materials so that less of each can be used.  Hybrid film is cost effective and very functional. Your car window tint shop can help you decide which type of car window tinting film is best for your vehicle.
