All rights reserved.In order to establish a repainting system when rust is hardly removed completely, the corrosion resistance of paints on the surface where rust remaining surface was studied. In order to change the properties of paints, we changed the kind of resin, antirust pigment and solvent for used undercoat, and confirmed the degree of influence on corrosion protection. Corrosion resistance of solvent type paint was less influenced by the type of resin and antirust pigment. On the other hand, antirust pigment greatly affected the anticorrosive property of aqueous epoxy resin paint. The results were focused on the effect of water solvent and antirust pigment on the remaining rust surface.
