The invention relates to an anti-corrosive coating agent for metal workpieces. For the purpose of good cathodic corrosion prevention, the anti-corrosive coating agent comprises an organic binder having a silicon-organic compound and particulate metal. The workpiece having an anti-corrosive coating is characterized in that the anti-corrosive coating comprises an organic binder having a silicon-organic compound and particulate metal. The method for producing an anti-corrosive coating on a workpiece is characterized by applying, in liquid form, a first coating, comprising an organic binder having a silicon-organic compound and particulate metal as the anti-corrosive coating, and then applying a second coating the composition of which preferably differs from that of the anti-corrosive coating.
La présente invention concerne un agent de revêtement anticorrosion pour métaux ainsi qu'une pièce dotée d'un revêtement anticorrosion. Selon l'invention, pour permettre une bonne protection contre la corrosion cathodique, l'agent de revêtement anticorrosion comprend un liant organique comprenant un composé de silicium organique et un métal particulaire. L'invention a également pour objet un procédé pour produire une revêtement anticorrosion sur une pièce, le procédé comprenant les étapes suivantes : application sous forme liquide, en tant que revêtement anticorrosion, d'un revêtement primaire comprenant un liant organique qui comprend un composé de silicium organique et un métal particulaire ; puis application d'un second revêtement dont la composition se différencie de préférence de celle du revêtement anticorrosion.
