Abstract

L'invention concerne une composition de revêtement de couche d'accrochage destinée à être utilisée dans un système de revêtement destiné à un substrat métallique comprenant au moins trois couches de revêtement. Le système comprend une couche de revêtement d'apprêt qui recouvre le substrat métallique, une couche de revêtement de couche d'accrochage qui recouvre la couche de revêtement d'apprêt, et une couche de revêtement de finition qui recouvre la couche de revêtement de couche d'accrochage. La couche de revêtement d'apprêt est constituée d'une composition d'apprêt, la couche de revêtement de couche d'accrochage est constituée d'une composition de couche d'accrochage, et la couche de revêtement de finition est constituée d'une composition de finition. La composition d'apprêt comprend un milieu de support d'apprêt et un inhibiteur de corrosion d'apprêt, l'inhibiteur d'apprêt ayant un mécanisme cathodique galvanique. La composition de finition est formulée pour donner une texture et un aspect de surface prédéterminés. La composition de couche d'accrochage comprend un milieu de support de couche d'accrochage et un inhibiteur de corrosion de couche d'accroche. L'inhibiteur de corrosion de couche d'accroche a un mécanisme de barrière.
