High Purity Thermal Spray Pure Zinc Wire 3.17mm for Anti-Corrosion Coating Applications

Product Description

Product Overview
Thermal Spray Pure Zinc Wire is a high-purity metallic wire primarily composed of 99.9% zinc, widely known for its excellent corrosion protection properties. Also referred to as zinc Thermal Spray Wire or zinc metallizing wire, it is silver-gray in color with a smooth surface finish. The wire is specifically engineered for thermal spray systems such as arc spray or flame spray, and it is commonly used to form sacrificial coatings on metal surfaces that are exposed to marine, industrial, or atmospheric environments.

Application Areas
Thermal Spray Pure Zinc Wire is ideal for providing a long-lasting protective layer against rust and corrosion. It is frequently used in the following sectors:

1. Bridges and Steel Structures – Enhancing durability against weathering.

2. Shipbuilding and Marine Equipment – Preventing saltwater corrosion.

3. Pipelines and Tanks – Protecting underground or exposed storage units.

Working Principle
During the thermal spray process, zinc wire is melted using a combustion or electric arc system and then atomized into fine droplets, which are propelled onto the substrate surface. Upon impact, these droplets solidify and form a dense, adhesive coating that acts as a sacrificial anode, protecting the base metal underneath.

Technical Parameters

• Long-lasting corrosion protection

• Easy to apply in both indoor and outdoor environments

• Compatible with multiple spray systems

• Reduces long-term maintenance cost

• Strong bonding with steel and concrete
