Type of Window Tint Film for preventing solar heat is able to be categorized as the followings.
is a first generation of window tint film. It is the cheapest film which prevents solar radiation by shielding with dyed color placed on an adhesive layer. However this film function basically is for visibility limitation, looking from outside feels smooth, dark and having privacy. Looking from inside still has good visibility. When it is used with car windows, looking from outside is black and dark. The disadvantage of this film is fading over time and the heat preventing of dyed film is not as good as it should be because of the heat absorbance of dyed color. Some heat may be removed by convection of outside wind while some heat is transferred to cabin.
This film prevents heat by solar reflecting of very small metal particles which embedded and invisible in film. Metal particles make glass stronger, resist to break and scratch than dyed film. Looking from outside feels reflecting like mirror. The disadvantage of this film is making reflect to other driver sights and tend to interfere mobile signal, GPS, active RFID (Easy/Toll Pass) or radio frequency signal/ electromagnetic wave.
This film has not any metal particles, so there is no problem of radio frequency signal/ electromagnetic wave interference or electronic device signal communication. With the carbon feature, it make feeling of dark, matt and outstanding/novel taste. Quality of carbon film is prevent infrared radiation (a composite of heat) about 40% which is better than dyed film, make inside cool, reduce fading of upholstery, reduce load of air conditioner in summer time. And another good point is not fading over time.
is the best quality film and most expensive. It has not metal particles, dyed color and carbon. The film uses the nonmetal/nonconductive ceramic particles for main composition in film structure. Ceramic is the best material for heat insulation and installed as the outside material of space shuttle for protecting aircraft from 1000 degree Celsius of friction heat while aircraft moving through the atmosphere of Earth. Ceramic film just appeared in the market recently and is proved itself to the valuable, reliable and performance. Ceramic film cuts the infrared radiation of solar heat off 50%-80% and prevent more heat than others despite of low dark film, while it has very good visibility in both of day and night time. Because of no metal composition, it has the best efficiency of all electronic device communication signal transmission (likes as carbon film) Ceramic film helps to reduce glare, reduce shattering of glass and difficult to fade over time, 25 times of last longer than dyed film and metal film. This film has the most efficiency to protect UV radiation, up to 99.9%. The disadvantage of ceramic film is heat absorbance in its own. If car doesn’t move, there will be less heat convection by wind from the outside film surface. The absorbed heat will transfer to the cabin.
At present, nano technology changed the concept of new material making or producing to the Bottom-Up Technology that means making from smallest things in the atom or molecule level. “Molecular reform” technology is used to reorder molecule and create crystal structure in order to make best structure and get new invention with the best desired quality.
Then the Nano-Crystal Cool film is produced by the technology of “Nano-Crystal to Thin Film Multilayer” in order to achieve the special desired feature in each layer as the followings.
1.
The “Nano-Crystal UV Inhibitor” layer has the special molecular order in the nano level to achieve not only the ability of 100% UV protection but also extend to the high frequency visible light (nearby UV). The light in this range that we have known as “Blue light” has high energy and is harmful to our eyes if your eyes are exposed too much and long time. The structure of the “Nano-Crystal UV Inhibitor” layer is able to protect the light of wave length 450 nm to 290 nm which is cover from blue light to UVA and UVB ray.
2.
The “Nano-Crystal IR Inhibitor” layer has the special molecular order in the nano level to achieve the ability of 95% protection of wide range Infrared, from 950 nm to 2,500 nm which is cover the infrared range of solar light coming to the earth.
3.
The “Nano-Crystal Pigment” layer has the special molecular order of inorganic molecule in the nano level and reform to specialized crystals which have ability to reflect the designated wave length light. So, we could specify color of pigment, visible light transmission and glare reduction as desired accurately.
With all of three layers of thin film which had been researched and developed by nano technology which is the proprietary of Kontrast, so this film, Nano-Crystal Cool series, presents the outstanding quality of cool and clarity.
Photochromic film is the film that darken when exposure to specific types of light of sufficient intensity, most commonly ultraviolet (UV) radiation and visible light that have short wavelength such as blue and violet light. In the absence of activating light the lenses return to their clear state. This photochromic technology is widely applied to lens of glasses as we know in the name of “Photochromic lenses or Automatic light adjusting lenses or Transition lenses”. With the state of the art of technology from Germany, the layer of photochromic, layer of Nano ceramic and the silver layer for reflecting heat ray are able to be composed. So this film is the best ultimate innovation of window films nowadays. However this type of film has higher production cost than others because there are many high quality film layers included and it need the high technologies for deposition of thin films.
Because of multilayer structure of this type of film, its thickness is 3-4 times more than general window films and the thickness is in the criteria of the safety film. That means, the glass installed the type of film will be safety glass with explosion proof. It is able to prevent shattering from accident and delay more time of robbery.
