Abstract:
The invention relates to a composition for applying a clear or translucent and colorless or nearly colorless emissive coating especially for cool roofing on a metallic surface comprising in a dispersion a) 50 to 300 g/L of at least one of clear or translucent organic polymeric substances of a binder, and b) 30 to 300 g/L of sheet silicate pigments having a TE value for the thermal emissivity of at least 0.40, having a particle size distribution of which dis in the range of 0.3 to 80 μm and having been comminuted, disintegrated, exfoliated or any combination of these to thin particles.There is further on provided a process for applying a clear or translucent and colorless or nearly colorless emissive coating especially for cool roofing on a metallic surface wherein a composition of the invention is applied on a metallic surface, wherein the coating is dried and wherein the dried coating has a coating weight in the range of from 0.2 to 2000 g/m.There is further on provided a clear or translucent and colorless or nearly colorless emissive coating as prepared with a composition of the invention as well as a cool element like a cool roofing element.
