Anti-corrosion paint composition and anti-corrosion paint film structure using the same

摘要

Provided is an anti-corrosion paint composition that has the same or better alcohol resistance as conventional glass flake-containing vinyl ester resin and is excellent economically.  The anti-corrosion paint composition comprises (A) an unsaturated polyester resin component containing (i) an unsaturated polyester obtained from a dibasic acid component and a polyhydric alcohol component and (ii) a polymerizable unsaturated monomer, and (B) glass flakes.  The dibasic acid component is composed of 70 to 100 mol% of an unsaturated dibasic acid and 0 to 30 mol% of a saturated dibasic acid, and the polyhydric alcohol component comprises 50 to 100 mol% of a glycol wherein the number of carbons in the main chain is 1 to 3 and the number of side chains is 0 or 1.
