The present invention relates to a process for coating a pre-treatment composition prior to an organic coating, as a protective composition, without pretreatment of an organic coating, with a pretreatment primer composition, with a primer composition, with a paint composition, or with a electrodeposition coating composition metallic surface with a composition , Wherein each coating composition, or a resulting coating thereof, contains particles based on at least one double layer hydroxide (LDH) phase as shown in the following general formula [1] [M 2 + (1 ± 0.5 ) -x (M 3 +, M 4 +) x (OH) 2 ± 0.75] A n - x / n and mH 2 O [1], Wherein M 2 + , M 3 +, and M 4 + are specific bivalent, trivalent, and tetravalent cations, wherein the cations M 3 + do not need to be present or the cations M 4 + need not be present, The neutral or charged molecules A comprising assemblies with said anions A and / or molecules A are selected from the group consisting of hydroxides, fluorides, carbonates, nitrates, sulphates, chromates, chromates, molybdates, From the group consisting of molybdates, phosphates, phosphonates, tungstates, vanadates, azoles, carboxylates, dodecylbenzenes, phenolic compounds, anionic surfactants and anions of biomolecules And / or wherein each one of the coating compositions, or a resulting coating thereof, is selected from oxides, double oxides, multiple oxides, hydroxides, at least one LDH phase, other anions A and molecules A Calcining a mixture of substances selected from the group true luer mainly those of calcination, at least in part, that is based on and / or partly or wholly thereof and contains the the rehydration after the LDH particles. |
