Metal Fluorocarbon Paint Steel Structure Bridge Renovation Anti-Rust Coating

Product Features:

Exceptional outdoor durability with a service life exceeding 20 years; excellent resistance to sunlight and weathering, providing UV blocking without fading, chalking, cracking, or yellowing.

Resistant to chemical media, with a paint film surface that is stain-resistant and easy to clean;

Effectively inhibits the growth of algae and mold;

Exhibits strong adhesion to various substrates such as cement, metal, and plastic.

Design Purpose:

Fluorocarbon paint is currently the highest-performing coating with outstanding physical and chemical properties. Its superiority over conventional paints lies in its weather resistance, self-cleaning capability, corrosion resistance, high-temperature melting resistance, and long-term color retention. It is used for protection in steel structure bridges, concrete bridges, metal curtain wall coatings, architectural steel structures, large venues, ports, docks, and coastal marine facilities.

Main Characteristics:

Exceptional weather resistance and durability.

◆ Contains F-C chemical bonds, ensuring high stability.

◆ Excellent chemical resistance.

◆ Superior anti-fouling performance; the paint surface can be cleaned with ordinary detergents.

◆ Dense and hard paint film, resistant to impact and abrasion.

Applications:

◆ Used for protection in steel structure bridges, concrete bridges, metal curtain wall coatings, architectural steel structures, large venues, ports, docks, and coastal marine facilities.

Surface Treatment: The surface must be sandblasted or shot-blasted to Sa2.5 grade as per GB8923 "Rust Grades and Preparation Grades of Steel Surfaces Before Coating." Areas that do not meet pretreatment requirements should be mechanically ground to St3 grade.

Usage Instructions

1. Application methods include spraying, rolling, or brushing. Spraying is recommended for metallic flash paints. 2. Before application, the paint must be stirred until completely uniform. If skin or particles are found, filter through an 80-120 mesh sieve. 3. Fluorocarbon paint is a two-component curing type. After mixing Components A and B strictly according to the ratio, allow 10 minutes for maturation before use. 4. At 20°C, the mixture will begin to gel after 6 hours and become unusable. Prepare paint as needed to avoid waste. Seal containers after use. Do not pour unused mixed paint back into the original container. 5. Adjust the application viscosity using the company's dedicated thinner. 6. Before applying the topcoat, ensure the substrate is clean, dry, free of oil, and dust-free to avoid adhesion issues.

Application Parameters:

Application Conditions

Surface treatment requires the previous coat to be dry, clean, and uniform. Substrate temperature should be between 5°C and 50°C, at least 3°C above the dew point. Relative humidity should not exceed 85%.

Remarks:

1. Although the above data are based on tests and accumulated experience, they are for reference only. Actual performance depends on factors such as film thickness, application environment (ventilation, temperature, humidity), underlying coatings, and overall compatibility. 2. This product is intended for professional use only. For applications outside the specified uses or under unknown conditions, we only guarantee the quality of the paint itself. 3. This manual has been updated and improved based on recent practical experience. This version replaces all previous editions. 4.
