According to the experts, such an energy saving coating is formulated through high-tech methods using tungsten oxide nano particles and highly transparent inorganic resin as the main raw materials. When the coating is coated on the surface of glass substrate, it can quickly form a transparent heat insulation film with a thickness of 8-10 μm. Under the premise of ensuring high transparency, the heat insulation film can shield most of the near infrared rays and almost of the ultraviolet rays with low cost and good energy saving effects. So, energy saving coating of nano particle size tungsten oxide is regarded as an important dingal material for the reconstruction of building glass.
