5 Micron Zinc Flake Powder
Product origin :CHINA
Delivery time :15-20 DAYD
Supply capacity :20MT/M
Product name: Zinc Flake Powder
Appearance: Lamellar/Flake Metallic Silver Gray Powder
Technology: Dry method and high-energy ball milling technology, multi-coated layer processing;
Advantages: Better dispersion, longer salt spray time, slowly sedimentation in the coating material
Application:
Daceomet/Geomet technology, Zinc-Cr Coating material,
Powder coating and painting for Boats, Warships, Automotive parts, Vehicle, Iron tower and the like;
Chemical property and features:
In electro-chemistry: Compared to the base metal “ Fe ” being protected, the Zn shows more negative charge and will be self-sacrificed in electric medium to protect the base metal, even the base metal being exposed because of the damage of the coating layer;
Sealing and tightness: the corrosion of the zinc powder (ZnCO3 and Zn(OH)2) deposits among the voids of the small zinc particles as filling stuff of the pigment, the electro-insulation makes it show the natures as sealing effectiveness;
Shielding natures: the lamellar powder shows parallel line in the surface of the coating film, as well as overlap and cross each other, which makes the water or corrosion medium difficult to be permeated that shows the anti-corrosion effectiveness.
