Product Description

National economy and the evolution of modern science and technology has brought about greater awareness to energy saving and environmental conservation.
The infrared layer on top of the ordinary glass may be good but it is insufficient in various circumstances as there is a need to cut off a huge thermal
radiation energy loss. In order to save energy, most people make use of heat reflective metal coating heat-reflective glass and a variety of films and
other products, to reflect the sun rays in the energy in order to achieve cooling insulation. Unfortunately some of these products are ineffective of
insulation, some have low light transmittance, and some require expensive equipments, complicated processes control and not conducive to the bigger
markets. Subsequently, a cost-effective transparent insulation coating is needed in the market to address this critical issue.

THE INSULATION PRINCIPLE OF COATING

Solar radiation energy is concentrated in the wave length ranging between 0.2μm and 2.5μm, the specific energy distribution is as follows: UV 0.2 ~ 0.4μm,
5% of total energy; visible area is 0.4μm ~ 0.72μm, 45% of the total energy; the nearest infrared region is 0.72 ~ 2.5μm, 50% of total energy. As a result,
most of the solar spectrum in the energy distribution falls within the visible and nearest infrared region accounts for nearly half of the overall infrared
energy. Infrared light can be a very good heat insulator as it has no effect on visual effects so it does not affect the transparency of glass. Therefore,
the infrared light provides an effective shield to allow visibility through the material. Transparent glass heat insulation coatings of the nano-semiconductor
material of the solar spectrum have the ideal selectivity, high transmittance in the visible region, whereas the infrared light has good shielding performance.
Mixing nano-semiconductor and nano-dispersed powder made of gold into the resin solution enables insulation coating to form a good insulating film on a
transparent glass surface.
