Passivation For Hot-Dip – Galvanizer \u2013 <\/span><\/strong>ADL-3P\u00a0<\/span><\/strong><\/span><\/h2>\n<\/div>\n<\/header>\n
\n

ADL-3P is a\u00a0<\/span><\/strong>Chromium III (Cr3+) passivation<\/span><\/strong>\u00a0chemical\u00a0for hot-dip galvanized (HDG) steel, used in\u00a0<\/span>a separate passivation tank<\/span><\/strong>\u00a0after the\u00a0<\/span>\"5\"cooling process.<\/span><\/p>\n

The product creates a thin transformation film on the zinc surface, reducing\u00a0<\/span>white rust<\/span><\/strong>\u00a0, enhancing corrosion resistance, and meeting the trend of replacing\u00a0<\/span>Chromium VI (Cr6+)<\/span><\/strong>\u00a0technology with environmentally friendly solutions.<\/span><\/p>\n

Developed by\u00a0<\/span>AD Chemicals (Netherlands)<\/span><\/strong>\u00a0, ADL-3P is a suitable choice for HDG lines that want to individually control the passivation process to optimize surface quality and corrosion protection.<\/span><\/p>\n
