Flake Zinc Powder Introduction
Release time：
2025-05-16
Flake zinc powder is a specialized metallic powder material characterized by its flat, plate - like particle morphology. Produced through advanced manufacturing processes, these zinc particles typically have a high aspect ratio, with diameters ranging from several micrometers to tens of micrometers and thicknesses in the sub - micrometer range. This unique structure endows flaky zinc powder with a series of excellent properties that distinguish it from conventional spherical zinc powder, making it an essential material in various industrial applications.

Key Advantages
Superior Corrosion Resistance:
One of the most outstanding advantages of flake zinc powder is its exceptional corrosion - resistance. When used in coatings, the flat - shaped zinc particles form a tightly - packed, overlapping layer on the substrate surface. This creates a physical barrier that significantly reduces the penetration of corrosive substances such as moisture, oxygen, and chemical agents. Additionally, zinc is a sacrificial metal. In the presence of an electrochemical cell, zinc will corrode preferentially over the base metal, protecting the underlying substrate through cathodic protection. This dual - mechanism of corrosion protection makes coatings containing flake zinc powder highly effective in preventing metal corrosion, even in harsh environments.
Good Dispersion and Film - forming Properties:
Flake zinc powder has good dispersion characteristics in various binders and solvents. Its flat shape allows it to be easily dispersed and oriented within the coating matrix or composite material, resulting in a uniform and smooth film formation. This property ensures consistent performance of the final product and is crucial for applications where surface quality and material uniformity are important, such as in high - end coatings and precision - made components.
