AQUEOUS ANTIRUST PAINT AND METALLIC PRODUCT COATED WITH AQUEOUS ANTIRUST PAINT

摘要

PROBLEM TO BE SOLVED: To provide an aqueous antirust paint excellent not only in long term antirust performance by thin coating but also adhesion performance between concrete and a coated matter, and an aqueous antirust paint-coated metallic product coated with the same.;SOLUTION: The aqueous antirust paint includes an epoxy resin emulsion, a water-soluble acrylic resin, an aqueous antirust agent, and an aqueous wetting agent. The ratio of an amount of epoxy resin composing the epoxy resin emulsion to a total amount of resin composing the epoxy resin emulsion and the water-soluble acrylic resin is 30% or more. The ratio of a total resin constituent in the paint is 10 mass% or more and 40 mass% or less, the ratio of the aqueous antirust paint is 0.1 mass% or more and 5 mass% or less, and the ratio of the aqueous wetting agent is 0.1 mass% or more and 5 mass% or less. The glass transition point of the water-soluble acrylic resin is 0°C or higher and 125°C or lower, and the acid value of the water-soluble acrylic resin is 80 mg/KOH or more and 240 mg/KOH or less.;COPYRIGHT: (C)2015,JPO&INPIT
