<p>isclosed is an anti-plating agent for use in hot-dip plating process, having the following two kinds of composition. The composition of the first kind includes an alkali silicate; boric acid, and alkali hydroxide, magnesia and/or magneium hydroxide, titania and/or titanium hydroxide, and at least one compound selected from a group consisting of alumina, aluminium hydroxide and alumina zol. The composition of the second kind includes an alkali silicate, boric acid, alkali hydroxide, magnesia and/or magnesium hydroxide, alumina and/or aluminium hydroxide, and at least one kind of titanium oxide and titanium complex oxide and/or at least one kind of zirconium oxide and zirconium complex oxide. These anti-plating agents have a good anti-plating effect and permit an easy separation of the coating film and, hence, can suitably be used in one-side hot-dip plating of steel sheets.</p> |
