XO series Nano Ceramic High Heat Rejection Window Film with Lifetime Warranty.
In 2021, KSB launches a new film product, an extremely high-performing Nano ceramic film-XO series. This film comes with no dye or metal elements, and the heat rejection come up to 99.5% at the wave length 1400nm and 98.7% at 950nm. This is the highest heat rejection film that KSB can offer. The thickness is 2mil, and from initial test with tinters, it is quite easy to work with. Color is brilliant with a light hue of green, not too much.
The new series XO Nano film comes with a lifetime warranty, and during the warranty period, color stability, bonding with the window are all warranted by the manufacturer.
Nano Ceramic Film- ceramic means a material or technology applied a film to enable it with certain features such as heat resistance. So, ceramics here means- or generally refers to a new type of material that makes the average particle size (D50) of the material less than 100 nanometers through various means and technologies. The main material is Nanometer cesium-doped tungsten oxide powder or Titanium Nitride.
Nano-Cesium-Doped Tungsten Oxide: It is one of the semiconductor materials with the highest spectral selectivity found to date. It is characterized by a high transmittance to visible light and a strong barrier in the near infrared region. The special properties of this material can completely replace expensive magnetron sputtering and other technologies, and are used for special needs such as solar film production, near-infrared identification, and near-infrared hot-melt processes.
Ceramic film has features such as
- High clarity
- High heat rejection
- high temperature resistance,
- pollution resistance,
- high mechanical strength,
- simple separation process,
- low energy consumption,
- Long life span.
XO series Nano Ceramic film is superior not only in terms of heat rejection but also, in terms of clarity. Nano ceramic film apply specially treated Nano particles to gain certain Optical and Thermal functions. One technic is important for the film to have high clarity, besides the quality of the Substrate-The distribution of Nano ceramic molecular structure. There are two ways of the Nano ceramic material Coating-Thousand degree sintering and hundred degrees stir. The Nano IR absorber comes in as powder, to get them coated on the films. To save cost and time, some just stirrer up and mix the heat rejection material with just hot water-this is an inexpensive way, but the disadvantage is obvious, the particles are not evenly coated on the film nor in uniform sizes. When the light comes through, they diffuse light in different angles and this can make the film foggy or alter the view or causing a low angle haze.
The Nano-powder itself is in a soft agglomeration state. We need to use wet grinding equipment and processes to separate the soft agglomeration. So they stay in a stable state. The powder needs to be burnt at 800-1000℃, so that big particles are burnt into more evenly uniformed size. A good quality Nano film will have high IR rejection, low reflectivity, and high clarity.
