Abstract (en)
[origin: EP0128514A2] In a process for treating the surfaces of aluminium heat exchangers which are provided with a corrosion-protective coating, the corrosion-protective coating is aftertreated, in order to apply an adherent, hydrophilic coating, with a dispersion which contains fine clay particles, preferably having a particle size of from 1 to 100 nanometres. The dispersion may additionally contain a surfactant, fine particles of silica or silicate and/or water-soluble synthetic resin. The weight of the coating produced by the aftertreatment should be from 0.01 to 5 g/m<2>, preferably from 0.1 to 1 g/m<2> (in the dry state).
