COATING/SEALANT SYSTEM, AQUEOUS RESIN DISPERSION BODY, METHOD FOR PREPARING AQUEOUS RESIN DISPERSION BODY, AND METHOD FOR ELECTRODEPOSITION COATING

摘要

PROBLEM TO BE SOLVED: To provide a coating/sealant system preparation method.SOLUTION: A method for preparing a coating/sealant system includes: (a) a step of adding sulfur functionality azole to a composition which contains phosphorylated epoxy resin derived from at least (i) polyepoxide and (ii) phosphorous acid; (b) a step of adding a base to a composition after at least a part of sulfur functionality azole is added; (c) a step of preparing an aqueous resin dispersion body neutralized by a base by adding water to a composition after at least a part of the base is added; (d) a step of forming coating by coating the base material with a coating composition containing the aqueous resin dispersion body neutralized by a base; and (e) a step of forming the coating/sealant system by deposing a sealant containing a sulfur-containing polymer on at least a part of the coating.SELECTED DRAWING: None
