Disclosed is a composition for applying a clear or translucent emissive coating on an aluminum containing surface. The composition includes, in a dispersion, 50 to 300 g/l of at least one of clear or translucent organic polymeric substances of a binder, and 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 &#x3bc;m and having been comminuted, disintegrated, exfoliated or any combination of these to thin particles. The composition additionally includes the reaction product of at least one aminefunctionalized organosilane and/or oligomer and/or polymer thereof and at least one fatty acid. The molar ratio of the amino group/s of the at least one amine-functionalized organosilane and/or oligomer and/or polymer thereof and of the at least one fatty acid is 1.2:1 to 1:2.
