ABSTRACT:
A corrosion-inhibiting poly(arylene sulfide) coating composition is described which comprises a mixture of a normally solid poly(arylene sulfide) resin, a corrosion-inhibiting agent selected from alkali metal nitrites, benzoates, phthalates; ammonium chromates, benzoates, phthalates; mixtures of alkali metal chromates and alkali metal borates; morpholine; or combinations thereof, dispersed in a liquid suspending agent. An illustrative coating composition contains 25 weight percent poly(phenylene sulfide) resin, 8 weight percent titanium dioxide, 33 weight percent water, 33 weight percent propylene glycol and 1 weight percent sodium nitrite. The coating compositions are useful in inhibiting the occurrence of corrosion during coating and curing of the coating compositions to iron and iron-containing alloys in the formation of cured poly(arylene sulfide) resin coated iron or iron-containing alloy laminates.
