Pure Zinc Powder 45-90 µm

About Pure Zinc Powder 45-90 µm

This pure zinc powder is produced for thermal spray applications where a dense, well-bonded zinc coating is required for galvanic corrosion protection. The 45–90 µm particle size range is selected to provide stable feeding and consistent melting characteristics in standard flame spray and arc spray equipment. When applied correctly, the resulting zinc layer acts as a sacrificial anode, corroding preferentially to protect the steel substrate in atmospheric and immersion environments.

Typical uses include coating bridge components, marine structures, industrial tanks, ductwork, and fabricated steel assemblies before painting or as a standalone protective layer. The powder is also evaluated for use in HVOF and plasma spray setups, depending on specific gun parameters and application requirements.

Key Features and Benefits

• Sacrificial corrosion protection: Provides active galvanic protection to steel surfaces, extending service life in corrosive environments.
• Controlled particle size: The 45–90 µm cut promotes smooth powder feeding and uniform melting in thermal spray guns.
• Versatile process compatibility: Suitable for flame spray and arc spray; can be evaluated for HVOF and plasma spray based on your equipment setup.
• Practical packaging: Supplied in sealed 5 kg tins, 10 kg tins, and 25 kg pails to maintain powder integrity and match your consumption rate.

Applications

Pure Zinc Powder 45-90 µm is used across industries where steel structures require long-term corrosion resistance without the size limitations of hot-dip galvanizing. Common application areas include:

• Bridge and infrastructure steelwork: Field-applied zinc coatings on girders, bearings, and connection plates.
• Marine and offshore components: Protective layers on ship hull sections, decks, and offshore platform structural members.
• Industrial tanks and vessels: Internal and external coating of water tanks, chemical storage tanks, and pressure vessels.
• Fabricated steel assemblies: Coating of welded fabrications, handrails, and structural frames before final painting.
• Repair and maintenance: Restoration of damaged galvanized coatings on existing structures without disassembly.

Selection and Handling Guidance

When selecting zinc powder for thermal spray, confirm that your feed system, nozzle configuration, and gas parameters are compatible with a 45–90 µm particle size distribution. Store powder in original sealed containers in a dry environment to prevent oxidation or moisture pickup. Always refer to your equipment manufacturer's guidelines for powder feed rates and spray distances. If you are unsure about process fit, SPA2Z can assist with technical consultation and grade selection based on your spray setup.
