FIELD: chemistry.
SUBSTANCE: invention relates to a curable film-forming composition containing: (1) a curable organic film-forming binding component and (2) a corrosion inhibiting component containing lithium silicate present in the curable film-forming composition in amount of 0.1–4.5 wt. % of lithium. Invention also relates to coated metal substrates comprising multilayer metal substrates with a coating containing said composition, as well as to a multilayered metal substrate with a coating comprising: (a) a metal substrate; (b) a first curable film-forming composition supported on said metal substrate; and (c) a second curable film-forming composition applied on at least a portion of the first curable film-forming composition. First and second cured film-forming compositions independently comprise: (1) a curable, organic film-forming binder; and (2) a corrosion inhibiting component containing lithium silicate, magnesium oxide and/or azole.
EFFECT: disclosed are curing film-forming compositions containing lithium silicates as corrosion inhibitors, and multilayered metal substrates with coating.
