Nano Zinc Powder for Anti-corrosion

Updated: 2026-08-06

Overview

Nano anti-rust zinc powder is a specialized form of zinc powder designed for corrosion protection. Its nano-sized particles enhance surface coverage and adhesion, making it more effective than traditional zinc powders. It is widely used in industrial applications where metal surfaces are exposed to harsh environments, such as marine, automotive, and construction sectors. The powder is produced through advanced manufacturing processes, ensuring high purity and consistent particle size distribution. Its unique properties make it a preferred choice for anti-corrosion coatings, providing long-lasting protection against rust and oxidation.

Physical and Chemical Properties

Nano anti-rust zinc powder exhibits several key physical and chemical properties that contribute to its effectiveness. The powder has a fine gray appearance and a high density of approximately 7.14 g/cm³. Its melting point is 419.5°C, and it boils at 907°C, making it stable under most industrial conditions. Chemically, the powder is insoluble in water but reacts with acids and alkalis. Its nano-sized particles provide a larger surface area, enhancing its reactivity and adhesion to metal surfaces. These properties make it highly effective in forming protective layers that prevent corrosion.

Main Applications

The primary application of nano anti-rust zinc powder is in anti-corrosion coatings for metal surfaces. It is used in paints, primers, and protective coatings for automotive parts, ship hulls, bridges, and industrial equipment. The powder's fine particle size ensures even coverage and strong adhesion to metal substrates. In addition to coatings, it is also used in galvanizing processes and as a filler in conductive paints. Its ability to provide long-term protection against rust and oxidation makes it indispensable in industries where metal durability is critical.

Safety and Storage

Handling nano anti-rust zinc powder requires adherence to safety protocols to prevent health risks. The powder should not be inhaled or allowed to come into contact with skin, as it can cause irritation. Use protective equipment such as gloves, masks, and goggles when handling the material. Storage conditions are crucial to maintaining the powder's quality. It should be kept in a cool, dry place away from moisture and oxidizing agents. Properly sealed containers are recommended to prevent contamination and degradation of the powder's properties.

B2B Procurement Guide

When procuring nano anti-rust zinc powder, B2B buyers should consider several factors to ensure quality and reliability. Verify the supplier's credentials and request material safety data sheets (MSDS) and certificates of analysis (COA) to confirm the product's purity and specifications. Price varies based on purity and quantity, with reference prices ranging from $15 to $30 per kg. Bulk purchases may offer cost savings, but it's essential to balance cost with quality. Additionally, consider the supplier's ability to provide consistent particle size distribution and reliable delivery schedules.
