Ok, I was searching on the net for a film that might be able to be applied to the headlight of a vehicle instead of veil. The reason is because veil is hard to apply and from what I can tell does not have a very long life. I found a company that is supposed to make such a film. The company is called CPFilms, I have contacted someone there but I had to leave a message so I don't know if they are still making the film or not.
The patent information is as follows:
PET window film coated with a 6-micron layer containing 30% to 60% by weight infrared-absorbing nanoparticles retains heat while transmitting visible light. CPFilms in Martinsville Va., began producing IR-absorbing films three years ago for car windows in the Far East. It has since extended the technology to its Vista architectural window films with different levels of visible-light transmission. CPFilms' parent company, Solutia, has patents on IR-absorbing layers of lanthanum hexaboride, antimony-tin oxide, and indium-tin oxide. Use of these metals in nanoparticle form is CPFilms' development (U.S. Patent 6663950, 2003). Tel: (276) 627-3000 * CPFilms Inc. World's largest manufacturer of solar control and safety window films for commercial, residential and automotive applications. Precision Coatings on Film
patent number 6663950
I have to try to find this stuff and if I can get my hands on it, it might be an alternative to veil for people who do not want to apply it. From looking at the patent it allows about 70% light output while absorbing at least 35% infreared light. Does anyone know what percentage infrared veil absords?
