Anti-corrosive coating composition precursor

摘要

An anti-corrosive coating composition precursor enabling easily obtaining an anti-corrosive coating composition using a polyaniline powder is provided. The anti-corrosive coating composition precursor comprises polyaniline, polyvinyl butyral and an alcohol-containing solvent and has a storage modulus G' of 0.01 to 300 Pa and a loss modulus G" of 0.01 to 100 Pa obtained by a frequency dispersion measurement at a temperature of 25 ± 1°C at a frequency of 0.1 to 100 rad/s.
