Superiority

zinc powder

Appearance: Lamellar fine 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 coating technology, Zinc-Cr Coating liquid material

Powder coating and painting for Vehicle, Radar, Ships and Warships, Tank, Automotive parts, 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 changed into solution in electrolyte 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 (mainly as 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 overlaping and crossing each other, which makes and avoids the water or corrosion medium difficult to be permeated for showing the anti-corrosion effectiveness.
