China Zinc Flake Powder factory and manufacturers

Zinc Flake Powder

Short Description:

Product name: Zinc Flake Powder
Appearance: Lamellar Metallic Silver Gray Powder
Technology: Dry method and high-energy ball milling technology, multi-coated layer processing;
Advantages: Better dispersion, longer salt fog 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(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.
