摘要: The invention relates to a method for protecting metallic substrate against corrosion which results in the formation of species X derived from metal. A coating composition based on (hetero)polysiloxanes produced by hydrolysis and condensation is applied hardened. inventive characterised that said comprises at least one Z reacts or interacts with metal form Y. Species Y has more negative enthalpy than X.
