The present invention provides a curable cathodic corrosion protection powder coating, which comprises a thermosetting resin, a zinc borate compound, a curing agent in an amount effective to cure the coating. Further, the present invention also provides a method of cathode corrosion protection which includes the steps of subjecting the substrate to a mechanical treatment, applying to said treated steel surface, the cathodic protective coating, and polarizing the coated material as a cathode.
L'invention concerne un revêtement pulvérulent durcissable de protection cathodique contre la corrosion qui contient une résine thermodurcissable, un composé de borate de zinc ainsi qu'un durcisseur en quantité suffisante pour assurer le durcissement du revêtement. De plus, l'invention concerne un procédé de protection cathodique contre la corrosion qui consiste à : soumettre le substrat à un traitement mécanique, appliquer le revêtement de protection cathodique sur ladite surface métallique traitée, et enfin, polariser le matériau ainsi revêtu comme une cathode.
