Abstract:

External cathodic polarization of lacquered tinplate specimens immersed in solutions of different organic acid anion types and pH was employed to study the delamination produced around a deliberately introduced defect in the coating. Attempts were made to utilize this technique as the basis for a rapid, simple and reproducible method for the evaluation and prediction of the suitability of lacquered tinplate samples exposed to different food media. Results of experiments conducted with three types of lacquers on tinplate in citric, malic, oxalic, tartaric, fumaric, lactic and acetic acids at pH's ranging from 2.5 to 6.0, showed good reproducibility as well as good agreement with results from an accelerated immersion test and with those from actual cases of canned foods.
