PROCESS FOR COATING METALLIC SURFACES WITH COATING COMPOSITIONS CONTAINING PARTICLES OF A LAYERED DOUBLE HYDROXIDE

摘要

Coating a metallic surface with at least one of a pretreatment composition prior to organic coating, with a passivation composition without intent for subsequent organic coating, with a pretreatment primer composition, with a primer composition, with a paint composition and with an electrocoating composition, wherein the coating composition includes particles on a base of at least one layered double hydroxide (LDH) phase characterized by the general formula [M2+(1±0.5)−x(M3+,M4+)x(OH)2±0.75]An−x/n.mH2O.
