Beschreibung
Zusammenfassung:	The invention relates to a layer material for corrosion protection and to a solar receiver having such a layer material. The layer material comprises a binding agent (13) consisting of a resin, containing at least one of the following substances: oligo- or polysiloxane, silicone resin, silicone, silicate, polyphosphate, and which is dissolved in a solvent; a pigment consisting of zinc microparticles (14) having an average diameter of at least 1 [mu]m, characterised in that a further pigment consisting of titanium oxide or silicon oxide nanoparticles (15) having an average diameter of no more than 100 nm is present in the layer material. The layer (11) advantageously has a self-healing effect (17) in addition to the corrosion protection effect thereof owing to the use of zinc particles (14).
