Nano tungsten trioxide, or WO3, is a photochromic material, so the explosion-proof heat insulation coating prepared by using nano particle size tungsten trioxide as a dingal material will be colored under sunlight (ultraviolet rays). That is to say, the glass to which the photochromic film is applied can play a role in shielding ultraviolet rays. You know, photochromism is a reversible process. So, when tungsten trioxide film is in an oxidizing environment, discoloration occurs.

It is reported that there are a lot of high energy consumption buildings in China currently. And it is because that there are lots of large area glasses, glass curtain walls. These glasses cause high energy consumption and light pollution. In this regard, the experts said that if energy-saving reconstruction is carried out in these places, it is possible to reduce energy consumption and improve the living environment. Among many energy-saving products, explosion-proof heat insulation coating of nano tungsten trioxide is more and more well-known. And nowadays more and more people are beginning to accept this high-tech heat insulation products.
