Abstract (en)
[origin: EP3415659A1] An alkali conversion treatment composition for magnesium and magnesium alloy may include 2 to 10% by weight of a phosphoric acid compound, 1 to 5% by weight of an inorganic metal sol, 0.03 to 0.3% by weight of a vanadium compound, 0.5 to 5% by weight of a basic compound, 0.01 to 0.1% of an acrylic resin and a remainder of water soluble solvent. The composition may form a uniform and dense chemical conversion coating on a surface of magnesium or magnesium alloy material, and may provide excellent corrosion resistance, topcoat painting adhesion and water resistance, and may not cause defects on a surface of the topcoat painting.
