Abstract: A quenching bath for treating metals comprises a 0.5-20 wt. % thermosensitive polymer dispersion having pH =4 and the polymer particle having Tg -30-+10 degrees C. The dispersion is thermosensitised by the addition of oxyalkylated amines or ammonia having inverse solubility (Thermosensitive dispersion is one which coagulates on heating). The metals are quenched and coated with an excellent temporary anticorrosion coating simultaneously.
