Application case: Anti-corrosion treatment of 4 storage tanks for Southeast Asian customers

Core pain points:

1:The original coating failed after two years and the maintenance cost was high.

2: Strong acid (sulfuric acid) and salt spray corrosion are severe, resulting in a 30% reduction in the tank wall thickness.

3: Construction requirements: Completion within 3 days, VOC emissions should be less than 150g/L.

Solution: One-component polyurea anti-corrosion coating (ready to use upon opening, no need to mix)

Features and benefits   

*High solid content, low VOC emissions

*The application method is simple and does not require professional polyurea spraying equipment. It can be applied by brush, roller, or high-pressure airless machine.

*The coating has good flexibility, strong leakage resistance, and excellent waterproof performance.

*Excellent resistance to chemical medium corrosion, capable of withstanding certain concentrations of acids, alkalis, salts, oils, organic solvents, etc

*Excellent adhesion, which can quickly and firmly bond to the surface of substrates such as concrete, steel, wood, glass fiber, etc

*Wide temperature range for use ranging from -50 ℃ to 120 ℃

*It is one component material, easy to apply, without the need for mixing, reducing labor costs

Construction steps:

1: Base surface treatment

Concrete: Grind and dry;

Steel: Sandblasted for rust removal, reaching Sa2.5 grade in accordance with ISO8501-1 standard.

2: Spraying construction

High-pressure airless spraying, 2 layers of film formation (total film thickness 500μm);

24-hour curing, delivery within 3 days.

3: Meet environmental protection standards

The VOC is only 95g/L, far below the industry standard.
