Title:
ANTICORROSIVE COATING COMPOSITION, METHOD OF CORROSION CONTROL USING THE COMPOSITION, AND COATED MOLDING
Document Type and Number:
Japanese Patent JP2021054932
Kind Code:
A
Abstract:
To provide an anticorrosive coating composition capable of developing sufficient anticorrosive effect so as not to spread corrosion by securing adhesion between a coated film and a metal even if generating unexpected coated film defects while securing barrier property of a factor inducing rust such as water, and oxygen particularly to a material made of a magnesium alloy, and capable of drying and curing at ambient temperature to a large-sized structural member such as a high-speed transport vehicle to exhibit good coating workability.SOLUTION: The anticorrosive coating composition is an anticorrosive coating composition containing an epoxy resin, and a curing agent including: a bisphenol type epoxy resin (A-1) having an average molecular weight of 470-900, and an epoxy equivalent of 180-1,000 g/eq.; a polymer type epoxy resin (A-2) having a weight average molecular weight of 10,000-100,000; and an amine-based curing agent (B), where the mass ratio of these constituent (A-1) and constituent (A-2) is (A-1):(A-2)=10:90-90:10 in terms of solid content.SELECTED DRAWING: None
