Abstract

See full text

The disclosure relates to a coating composition comprising a resin system comprising an organic film-forming resin and optionally a curing agent reactive with the organic film-forming resin, a lithium salt with a solubility in water in the range from 0.01 to 120 g/L at 20° C., selected from the group consisting of lithium carbonate, lithium phosphate, lithium bicarbonate, lithium tetraborate, and lithium oxalate, and a zinc salt of 2,5-dimercapto-1,3,4-thiadiazole (DMTD), wherein the zinc salt of DMTD is present as solid particles, the surface of which is at least partially covered by a layer of a film-formed polymer. The zinc salt of DMTD was shown to have a synergistic effect on reinforcement of barrier properties of a protective layer that is formed in a coating defect due to the presence of the lithium salt. In addition, the coating composition has an improved pot life.
