Huper Optik first looked at traditional dyed and metallic window tints to see what they liked and disliked about them to get the best product in the marketplace. They first looked at the color stable dye and found that they liked the looks of it, but did not like how the color stable dye would turn purple over time and it also does NOT have any heat rejection. The next type of tint they looked at was the metal window tints that were made with aluminum particles spattered throughout the film. The good part of those window tints was that it had good heat rejection; the bad part was that it looked too much like a mirror. It was also found that the aluminum caused problems with radio reception, navigation devices, cell phones, and anything else that needed a signal. So Huper Optik took all of that data and came up with nano-ceramic film which is the pioneer of the ceramic window films. NASA uses this technology on the shuttles ceramic tiles to deflect the heat when the shuttle is returning back to earth. They put that same nano-ceramic technology into a window film and called it Huper Optik. The great part of the new technology is that it has NO dyes so it can never turn purple or even change any color at all, it also has NO aluminum in it so it does not interfere with signal or frequency. The best part of this window film is the heat rejection and clarity, which are both far superior to any other tint on the market. However, the thing we like the best about this film is the aesthetics. The look is one of a kind. There is no other film that can touch this window film and it's warranty.
