Problems solved by technology

However, the evaporation coating has the following disadvantages, such as the metal coating is easy to oxidize, the metal on both sides of the evaporation coating reflects visible light, which affects the perspective effect of the glass, the maintenance cost of the evaporation equipment is high, and the production energy consumption is large, etc.
Solutia Inc. is the world's largest window film company, nano optics It is a wholly-owned brand of the company. This brand has developed a nano-heat insulation film formed by molybdenum trioxide through magnetron sputtering. Molybdenum trioxide can absorb infrared rays and cause heat insulation film and substrate glass to heat up, which is prone to secondary Secondary radiation transfers heat into the window, weakening the insulation effect
