Product classification:
Product features
Product Details
Product appearance: scaly
Product characteristics: after nano processing and multi-layer coating treatment, it has the characteristics of slow sedimentation, high coating hardness, long salt spray time, good dispersion and strong shielding ability.
Application: Mainly used in the field of high performance zinc aluminum coating. It is also widely used in organic and water-based coatings, surface treatment of ships, cars, high-speed railways, power facilities, steel structures and buildings.
Application mechanism and characteristics: flake zinc aluminum alloy powder combines the advantages of flake zinc powder and flake aluminum powder, and achieves balance in material preparation, corrosion resistance and coating appearance. Zinc aluminum alloy has good ductility, scale specification is easy to control, and higher specific surface area of scale can be conveniently obtained; The flake zinc aluminum alloy powder not only has the effective anodic protection effect of pure zinc layer on the steel substrate, but also can improve its corrosion resistance because it contains enough Al to form a complete Al2O3 protective film. Due to the addition of aluminum, the flake zinc aluminum alloy coating also has excellent metallic luster that pure zinc powder does not have. At the same time, zinc aluminum alloy powder also avoids the problem of uneven coating solution caused by different densities of zinc powder and aluminum powder in the coating, and is an ideal anti-corrosion pigment for chromium free zinc aluminum coating.
