New Window Film Patent Granted This Summer
The U.S. Patent Office granted a new window film patent this summer. Below is the patent information including the inventor-written product abstract.
Patent: #8,246,848:
Process for Producing Base Material for Forming Heat Shielding Film
Date Filed: September 21, 2006
Date Granted: August 21, 2012

Abstract: There is provided a production process of a heat-ray shielding film-formed base member comprising the steps of mixing a sol solution, formed by using a starting raw material of trialkoxysilane or trialkoxysilane and tetraalkoxysilane, with a solution in which tin-doped indium oxide ultra-fine particles are dispersed, to make a treatment agent; and applying the treatment agent to a base member. In this production process, the treatment agent has an organic solvent having a boiling point of 100-200 degrees C as a dispersion medium, and the application is conducted by a means by bringing a member retaining the treatment agent into contact with the base member or by a means by spraying the treatment agent, thereby adjusting haze value of the film to be formed to 0.5% or less.

Cool Lines
HanitaTek’s new auto film lines are cool—Cool Coal and Cool Crystal. The Cool Coal line offers VLT options of 5, 18, 28, 38 and 50. The film is non-metal charcoal and is constructed to shrink more easily.

The Cool Crystal line is available in VLT options of 4, 12, 20 and 35. High heat rejection, maneuverability and a charcoal tint are features the company highlights.

Clear Tint
According to 3M, its crystalline film allows 40 to 90 percent visible light transmission (VLT) and rejects between 90 and 97 percent of the sun's IR rays while blocking up to 60 percent of heat transmission. The film is available in a nearly-clear VLT that the company says still offers many benefits of a dark tint film. Glare reduction of 55 percent is also available with this film.

First Class Film
Nexfil has debuted a new series of heat-shielding film, First Class. The company says that the new film overcomes the previous limitations of heat absorption value in existing IR and Sputter films. The First Class series will include five classes used for automotive front and side windows. The A-70 film will offer a VLT of up to 74 percent and a glare reduction of 19 percent.
