  • Patent number: 11542396
    Abstract: 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 d50 is in the range of 0.3 to 80 ?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.
