Abstract

The heat insulation coating includes the particles (secondary particles) of the silica aerogel (i) and the silica-based binder (ii). The thickness of the heat insulation coating is several 10 to several 100 μm. The particle size of the secondary particles is distributed in a range from the lower limit Rmin to the upper limit Rmax. The lower limit Rmin is 10 nm. The upper limit Rmax is equal to the coating thickness of the heat insulation coating.
