According to experts, such heat insulating glass coating is a liquid material with high transparency, high hardness and super heat insulation performance. Tested by the National Building Materials Testing Center, the coating has excellent spectral selectivity and stability. The coating film is crystal clear of thickness of 7-9 microns. The visible light transmittance of such coating film is above 70%. Also, the coating film can shield more than 99% of ultraviolet rays. And the near-infrared shielding rate is over 80%. Therefore, the temperature difference of the exposed object reach 10°C or above. And the indoor temperature difference reaches 3°C-6°C. It is estimated that the energy saving rate is as high as 25%-30%.
