Abstract

The quality of electro‐tinplate formed under different plating conditions from the stannous sulphate‐eresolsulphonic acid bath has been compared by the thiocyanate and hot‐water porosity teat and by exposure in a humidity chamber. Within the ranges examined, the quality improves with increase of tin concentration of the electrolyte and with decrease of current density. There is an optimum concentration of eresolsulphonic acid, defending on the tin content, liaising the temperature of the electrolyte impairs the quality of the deposits. No significant improvement was obtained by the addition of commercial wetting agents.
