MB210 Self-drying Acrylic Topcoat (Color) Paint

Product Introduction:

This product is a single-component, self-drying acrylic topcoat specifically designed for the protection and decoration of steel structures. It utilizes advanced low-hydroxyl acrylic polyol resins, combined with a superior pigment and additive formula. This coating dries quickly under natural conditions, is easy to apply, requires no additional hardener, and significantly improves construction efficiency. Its film possesses excellent weather resistance, gloss retention, and color retention, effectively resisting UV rays and external corrosion, providing long-term and stable protection and aesthetic effects for steel structures.

characteristic:

1. Excellent weather resistance and durability: Made with high-quality acrylic resin, the paint film can effectively resist the erosion of harsh weather such as ultraviolet rays and acid rain, maintaining its gloss and color for a long time, and is not prone to yellowing, chalking or fading.

2. Excellent gloss and color retention: The paint film has vibrant and full colors and long-lasting gloss, ensuring that the appearance of buildings or equipment remains new for many years.

3. Quick drying: It dries quickly at room temperature, shortening the application interval and improving overall coating efficiency.

4. Single-component design for convenient construction: No need to mix hardener, it can be used immediately after opening the container, reducing human error during construction and making operation simpler.

5. Good adhesion: It has good adhesion to treated steel structure primers or intermediate coats, forming a stable protective layer.

6. Diverse color options: Various colors can be customized according to customer needs to meet different design and decoration requirements.

use:

This product is primarily used as a topcoat layer in steel structure coating systems, suitable for applications requiring high aesthetics and weather resistance, such as:

1. Large steel structure buildings: such as stadiums, factories, bridges, and steel frame structures.

2. Outdoor machinery and equipment: such as cranes, construction vehicles, storage tanks, pipelines, etc.

3. Public facilities: such as streetlights, traffic sign poles, and outdoor billboards.

This product is recommended to be used in conjunction with a suitable steel structure primer and intermediate coat for optimal protection and aesthetics.

It is recommended that the coating thickness be at least three times the maximum roughness (Rz) to achieve a good protective effect.

Instructions for use:

Surface treatment requirements:

Use a solvent to remove visible grease, oil, lubricants, cutting fluid, and other soluble contaminants from the metal surface that may affect adhesion, or use other methods to prepare the surface condition for the coating application, following the SSPC-SP1 surface treatment standard to prepare for subsequent protective coating applications.

The steel structure surface must be sandblasted to Sa2.5 (very thorough sandblasting) or SSPC-SP10 grade. Without using a magnifying glass, at least 95% of the surface area should be free of any visible oil, grease, dust, dirt, scale, rust, coatings, oxides, corrosion products, and other foreign matter. The surface roughness should be in the range of Rz 30-75μm.

Power tool treatment must meet St 3. This standard defines the use of power tools (such as power wire brushes, grinders, abrasive discs, etc.) to remove loose rust, scale, old coatings, and other foreign matter from steel surfaces until the surface has a metallic sheen. However, minor scratches and discoloration are permissible. It is equivalent to SSPC-SP3 in the US SSPC standard.

Surface defect treatment: This includes weld slag, burrs, cracks, and holes. These defects affect the adhesion and protective effect of the coating and should be removed or repaired as much as possible.

After surface treatment, a thorough inspection should be conducted to ensure that there are no contaminants or defects such as oil, grease, dust, dirt, scale, rust, welding slag, or burrs before proceeding with the next step.

Under any atmospheric conditions, it is best to perform the coating work within 1 hour after the completion of the "surface treatment" procedure, and no later than 8 hours after the "surface treatment".

Different coatings have different requirements for surface cleanliness and roughness. Please discuss this in detail with our sales staff before using this product.

Construction environment requirements:

Coating application should be carried out under suitable environmental conditions to ensure the quality of the coating. The following factors should be considered:

Temperature: Please construct within the recommended temperature range. Generally, it is not advisable to construct in environments below 5℃ or above 40℃.

Humidity: Relative humidity should not exceed 85%. Avoid construction in humid or rainy weather.

Wind speed: Excessive wind speed will affect the spraying effect; avoid construction on windy days.

Surface temperature: The surface temperature of the steel should be at least 3°C ​​higher than the dew point temperature to avoid condensation on the surface.
