Anticorrosion primers contained a poly(vinyl butyral) resin(I), an organo functional silane(II), a borate or polyphosphate H3PO4, a phenolic resin, and a metal powder. Thus, Hitanol 4020(phenolic resin) 11, I 9, KBM 303(II) 0.5, yellow Fe oxide 3, phthalocyanine blue 0.3, carbon black 0.3, Al polyphosphate 2.5, talc 1, Al powder paste 5, Ba metaborate 2.5, org. bentonite 1, BuOH 11,Me2CHOH 22.9, and PhMe 30 parts were kneaded and ground, and the mixt. was mixed(80 parts) with 20 parts mixt. of 85% aq. H3PO4 9, water 5, and Me2CHOH 86 parts to give a coating compn.
