Abstract

Described is a process for protecting a metallic substrate against corrosion resulting in the formation of a species X, derived from the metal, wherein a coating composition based on (hetero)polysiloxanes prepared by hydrolysis and condensation processes is applied to the substrate and cured, and which is characterized in that the coating composition comprises at least one species Z which reacts or interacts with the metal to form a species Y having a more negative formation enthalpy than the species X.
