A method for producing a low VOC anticorrosion coating composition, an anticorrosion coating film, a base material with a coating film, and a base material with a coating film.

摘要

PROBLEM TO BE SOLVED: To form a coating film having excellent oil resistance, solvent resistance, chemical resistance and corrosion resistance, and a coating composition capable of forming a coating film having excellent balance of topcoat coating compatibility in addition to these performances. To provide a coating composition which is a product, has a low VOC, and is excellent in drying property and coating workability. SOLUTION: A bisphenol type epoxy compound (A) having an epoxy equivalent of 200 or less, an amine-based curing agent (B) having a cyclic structure, a silane coupling agent (C) having an epoxy group, and a flat pigment (D). And / or a pigment (E) other than the flat pigment (D) is contained, and the content of the silane coupling agent (C) is 5 to 20% by mass, satisfying the following (I) or (II). , Low VOC anticorrosion coating composition. (I) The mass ratio of (A) and (C) is 1.0: 0.1 to 0.5. (II) Contains two or more of the above (B) [Selection diagram] None
