  • the subject matter coating material can be applied to the galvanized steel sheet materials where the desired surface porosity is obtained, and the coating materials can be held on the surface of steel sheet materials.
  • Coating material can also be applied to the galvanized steel sheet materials. Under this title, said process steps can be applied. However, in order to be able to apply coating materials to galvanized steel sheet materials, surface porosity must be applied which is different from galvanized steel sheet materials. Processes are applied for forming surface porosity at a value between 1 and 1.5 R a to the galvanized steels in said SPM rollers. SPM rollers must have a value between 2 and 4 R a in order to provide the desired surface porosity to the galvanized steel sheets. As a result of the realized processes, the subject matter coating material can be applied to the galvanized steel sheet materials where the desired surface porosity is obtained, and the coating materials can be held on the surface of steel sheet materials.
  • the steel product coated with the subject matter coating material is an invention which is subjectable to mass production and which is applicable to industry in order to improve anti- corrosive effect characteristics, easing of forming, high temperature resistance and improve the dusting and fingerprint prevention performances.

Abstract

La présente invention concerne un matériau de revêtement afin d'améliorer les caractéristiques d'effet anticorrosion, la facilité de formation, la résistance à haute température et d'améliorer les performances de prévention de poussière et d'empreintes digitales de matériaux en acier qui ont été soumis à des procédés de zingage utilisés dans la production de biens d'équipement de la maison tels que l'automobile, le radiateur, les produits blancs et la télévision, et un acier revêtu dudit matériau de revêtement. Par conséquent, le revêtement selon l'invention concerne un acier comprenant un matériau de revêtement caractérisé en ce qu'il comprend au moins un chrome (+3) comprenant du phosphate ou au moins un composé nitrate ; au moins un acide carboxylique, au moins un composé silane afin d'améliorer les caractéristiques d'effet anticorrosion, la facilité de formation, la résistance à haute température et d'améliorer les performances de prévention du poudrage et des salissures ou des taches au moyen d'une application sur les surfaces de matériaux en acier qui sont soumis à des procédés de zingage.
