RUST INHIBITOR COMPOSITION AND RUST INHIBITOR-COATED STEEL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a rust inhibitor composition which is excellent in UV deterioration resistance and with which further progress of corrosion while rust coexists can be inhibited.SOLUTION: The present inventions relates to a rust inhibitor composition containing an alkyd modified acrylic resin and an organic solvent, the alkyd modified acrylic resin is obtained by modifying acrylic resin with oil modified alkyd resin, and is composed of an acrylic resin part (a), an alkyd resin modified part (b) and a fatty acid-modified part (c), and contains (a) of 50 to 90 wt.%, (b) of 5 to 25 wt.% and (c) 5 to 25 wt.%.
