Abstract
Multi-layer composite product, featuring low emissivity in the mid-infrared band (as wavelength range 2,5-5 μm) and far-infrared (as wavelength range 8.0-14.0 μm) bands, as well as low reflexivity in the near-infrared (at a wavelength range of 0.7-2.5 μm) and in the visible (as wavelength range 0.3-0.7 μm) bands, including a base constructed with low-density and/or high thermal-resilience structural materials, covered with optionally doped coating, and where, between the base and the coating, at least one intermediate layer of metals or metal oxides is planned for insertion.
