Is it environmentally friendly?

Yes, low-VOC options help reduce pollution.

What is the difference from zinc plating?

Coating is a spray process, not an electrochemical one.

How effective is its corrosion resistance?

Provides good cathodic protection, though not as durable as hot-dip galvanizing.

Is it suitable for on-site repair?

Yes, easy to maintain and reapply when needed.

What is the thickness range of zinc coating?

10-100μm, adjustable depending on application.

Processing Overview

Description: Zinc coating is a spray or dipping process that applies zinc powder or zinc alloy to a surface, typically in a thickness of 10-100μm. The process includes surface preparation, coating, and curing, and can be categorized as cold-dip galvanizing or hot-spray galvanizing.

Applicable materials: Steel, iron, and alloy steel structures.

Visual Appearance: Gray or silver-gray hues, with a rough or smooth surface, giving the appearance of a rust-resistant coating.

Advantage

Highly Effective Corrosion Resistance: The zinc layer provides cathodic protection against rust, making it suitable for outdoor structures such as bridges.
Easy Application and Repair: Can be sprayed on-site for easy repair; costs are lower than hot-dip galvanizing.
Flexible Thickness: Adjustable to suit environmental requirements, enhancing adhesion.
Good Electrical Conductivity: Suitable for electrical applications such as grounding.
Environmentally Friendly: Low volatile matter emissions reduce on-site contamination.
Impact Resistance: The coating is flexible and resistant to mechanical damage.

Precautions

Surface Preparation: Sandblasting or acid cleaning may be required, which may affect adhesion.
Thickness Testing: Ensure uniform coating application and test dry film thickness.
Environmental Limitations: Suitable for mildly corrosive environments, tested for salt spray resistance.
Design Considerations: Allows for coating thickness variations; avoid high-temperature applications.
Quality Standards: Comply with ISO 2063 or ASTM A780, and check coverage. Safety measures: Use protection when spraying and control dust emissions.
