Pure Zinc Powder [-200+400]

About Pure Zinc Powder [-200+400] for Thermal Spray

This zinc powder is manufactured to a controlled particle size range of -200+400 mesh, making it suitable for standard thermal spray feed systems. The narrow cut helps achieve stable powder feeding, consistent melting, and uniform coating deposition. When applied correctly, the resulting zinc coating provides galvanic protection to ferrous substrates, sacrificing itself to prevent base metal corrosion in atmospheric and immersion environments.

Typical users include applicators servicing bridges, marine structures, water tanks, and industrial machinery. The powder can be sprayed via combustion flame or electric arc systems, with HVOF and plasma options available depending on the specific coating density and bond strength required. Buyers should verify process compatibility with their equipment manufacturer before ordering.

Key Features and Benefits

• Controlled particle size: -200+400 mesh cut minimizes fines and oversize particles for consistent feed rates and deposit efficiency.
• High purity zinc: Designed to produce coatings with excellent sacrificial corrosion protection on steel substrates.
• Process versatility: Compatible with flame spray, plasma spray, and HVOF systems (process suitability to be confirmed based on exact equipment).
• Flexible pack sizes: Available in 5 kg tins, 10 kg tins, and 25 kg pails to match project scale from testing to full production.

Applications

Pure Zinc Powder [-200+400] is used across industries where steel structures require long-term corrosion protection without the size limitations of hot-dip galvanizing. Common application areas include:

• Bridge and structural steel coatings: Field-applied zinc coatings for new construction and maintenance of highway and railway bridges.
• Marine and offshore components: Sacrificial coatings on ship hulls, decks, offshore platform legs, and subsea equipment.
• Water and wastewater tanks: Interior and exterior protection of storage tanks, penstocks, and treatment plant steelwork.
• Industrial machinery repair: Restoration of corroded shafts, bearing housings, and pump casings where dimensional build-up and corrosion protection are both needed.

Selection and Handling Tips

When specifying zinc powder for a thermal spray job, confirm that your feed system can handle the -200+400 mesh range. Finer or coarser cuts may be required for specific gun types. Store powder in sealed, dry conditions to prevent oxidation or moisture pickup that can affect flowability. Always run a trial patch to verify adhesion and coating density before committing to a full production run.
