Fumin Coating
Reduce heat in summer In Winter Keep Warm Save energy
Fumin Coating
ATO and ITO known as semiconductor technology are commonly
applied to the touch panel etc. in order to absorb Infrared. These
Nano size metals, tolerate up to 180 °C, can be applied with a
sponge or with a roller at room temperature.
It is a great technology that will stop the heat and ultraviolet rays coming through the glass, however it will impair the value of the glass if there are unevenness, distortion, dripping on the glass. The solution to this problem lies in using ”FUMIN COATING spray gun method”.
Fumin Coating
Shading Coefficient is to quantify the amount of light coming through the window. To be effective, Shading Coefficient is lower the better. The dark film or reflective glass were believed to be good.
The latest window film cuts the heat & UV without blocking the light. Some mixed ITO and ATO to glue and those have the effect of the photo catalyst by absorbing the UV, however, these adhesive would result decomposition and discoloration.
FUMIN COATING, the world’s most advanced nanotechnology with its 2μm thick, its performance is not possible to measure by thin-film thermal conductivity meter. It is possible to measure if the thickness of temperature sensitive paint is more than 50μm. Therefore, we compare with those already measured.

After 375W infrared light irradiation for 1 minute,
the both sensors on metal plates detected almost
the same temperature.
SC of film is 0.57
Saving Energy calculation
（0.9－0.57）÷0.9ｘ100＝37％ of energy saved.
