A COMPOSITION FOR COATING STEEL MATERIALS CONTAINING CARBON NANOTUBE AND A MANUFACTURING METHOD THEREFOR

摘要

A steel sheet coating composition containing carbon nanotube is provided to ensure excellent chemical resistance, abrasion resistance, heat resistance, and fire retardancy without containing a chrome as a harmful component. A steel sheet coating composition containing an inorganic etchant comprises aqueous resin composition containing aqueous resin and water, water dispersible silica as an inorganic anticorrosive additive and carbon nanotube.
