Abstract

Compsn. contains the following quantities by wt.: HF 5-10%, H3P2O5 30-50%, HCHO 5-10%, ethylene oxide-monylphenol condensate 20-40%, butyne-1,4-diol 10-20%. The compsn. increases the surface pickling of the metals, decreases surface cracking, prevents attack of the base metal, improved the surface condition of the treated metal, increases the life of the bath and decreases the surface tension of the bath.
