china flake zinc powder for geomet coating

Product Overview

Description

 

Product name: Flake 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 technology, Zinc-Cr Coating material,

Powder coating and painting for ships and 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 will be changed into solution in electrolyte to show the effectiveness, 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.
