MANUFACTURING METHOD OF HIGH ADHESION AND HIGH CORROSION RESISTANCE STEEL MATERIAL, AND COATING FILM ADHESION IMPROVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique which obtains constantly stabilized high rust resistant and corrosion resistant effects utilizing a primer containing conductive polymer particles.;SOLUTION: The manufacturing method of a high-adhesion/high-corrosion resistance steel material comprises the steps of applying a primer containing the conductive polymer particles as an effective ingredient to a steel material and then applying an epoxy type, a urethane type or fluorine type resin coating containing an isocyanate type compound as a curing agent thereon. The coating film adhesion-improving method comprises the steps of applying a primer containing the conductive polymer particles as an effective ingredient on the steel material to be protected and then applying an epoxy type, urethane type or fluorine type resin coating containing an isocyanate type compound as a curing agent thereon.;COPYRIGHT: (C)2007,JPO&INPIT
