ABSTRACT:
A composition for water-repellent treatment of zinc and zinc alloys which comprises a non-ionic polymeric compound having both hydrophilic and hydrophobic groups in the molecule, a polyacrylic acid salt and a balance of water. The composition can be used in a method for water-repellent treatment of zinc and zinc alloys which comprises the steps of immersing zinc or zinc alloys which has been subjected to a conversion treatment, then washing it with water and drying the same. The use of the water-soluble composition for water-repellent treatments permits considerable reduction of the contact area between the repellent-treated metal material and moisture which becomes a cause of corrosion under the corrosive environment in which water and oxygen coexist and this accordingly results in the improvement in the corrosion-resistance of the metal material.
