Problems solved by technology

[0003] In general, the weather resistance of the primer coating film formed from the epoxy resin coating composition is poor, so the interlayer adhesion with the top coating film and the physical properties exhibited by the laminate with the top coating film, etc. Topcoat coating suitability is easy to decline
In particular, when the time from primer coating to top coat coating of the epoxy resin coating composition is prolonged, there is a problem that the interlayer adhesion between the formed primer coating film and the top coating film is insufficient.

Abstract

The present invention relates to an anticorrosion coating composition, an anticorrosion coating film, a substrate with an anticorrosion coating film, and a method of manufacturing a substrate with ananticorrosion coating film. The anticorrosion coating composition contains (a) an epoxy resin, (b) a polyvinyl alkyl ether (co)polymer, and (c) an amine-based curing agent.

Description

Technical field [0001] The invention relates to an anti-corrosion coating composition, an anti-corrosion coating film, a substrate with an anti-corrosion coating film, and a method for manufacturing a substrate with an anti-corrosion coating film. Background technique [0002] In the prior art, (large) steel structures such as ships, bridges, storage tanks, complete sets of equipment, offshore buoys, and offshore oil pipelines are coated with a coating film obtained from an epoxy resin-based anticorrosive coating composition in order to prevent corrosion . According to the use and purpose of the above-mentioned steel structure, in order to impart aesthetics, weather resistance, corrosion resistance, and antifouling properties, various resin-based top coating compositions are coated on such a coating film to form a top coating Coating film. For example, the bottom of a ship is coated with an antifouling coating composition that prevents the adhesion of aquatic organisms such as ...
