is the patent information including the inventor-written product abstract.
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.

In addition to its new film line Rage, Johnson Window Films is offering
its Renegade and Marathon films. Both the Renegade and Marathon lines
are available in Universal black with multiple levels of visible light
transmission (VLT). The Renegade line is a dual-ply dyed film, while Marathon
offers a hybrid construction that combines an aluminum layer with an impregnated
dyed film. All three films are backed under a manufacturer’s warranty
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.
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.
