High-build Water-based Special Paint for Steel Structures

High-build Water-based Special Paint for Steel Structures

Product Introduction:

It is a single-component, thick-bodied water-based paint specially designed for steel structures, composed of water-based acrylic-modified alkyd emulsion, pigments, anti-rust pigments, additives, deionized water, and other components.

Product Usage:

Suitable for anti-corrosion coating on various metal surfaces such as steel structures, workpieces, pipelines, and coils, it provides effective rust and corrosion protection in mildly corrosive environments.

Product Features:

Non-toxic, fast drying, thick coat applicable, high rust resistance, excellent water resistance.

Application Precautions:

1. Substrate Treatment: The construction substrate surface must be clean, dry, and free from loose paint layers, grease, rust, and other contaminants.

2. Construction Environment: The ambient temperature for construction should be ≥5℃, humidity ≤85%, and the surface temperature of the workpiece being worked on should be ≥5℃.

3. Application Methods: Airless spraying, air spraying, brushing, and roller coating.

4. Dilution Ratio: Mix with clean tap water at 5% to 25% and stir evenly until reaching the desired construction viscosity.
