Low radiation coating film, manufacturing method thereof, and functional building material for windows including the same

摘要

An object of the present invention is to provide a low radiation coating film having excellent mechanical properties such as abrasion resistance, chemical properties such as moisture resistance, corrosion resistance, acid resistance, base resistance, and thermal properties, and Providing functional building materials for windows. A low radiation coating layer; and a top coating layer, the top coating layer including a metal layer, a metal oxide layer, and a metal oxynitride layer sequentially from the low radiation coating layer. Low radiation coating film having multilayer structure, method for producing the same, and functional building material for windows including the same. [Selection] Figure 1
