Application Areas:

Widely applicable to fire protection of steel structures in industrial plants, stadiums, airport terminals, gymnasiums, TV towers, metallurgy, power equipment, and chemical industries.

 

Main Characteristics:

It has excellent properties such as thin coating, fast drying, easy construction, brushable, sprayable, rollable, corrosion resistance, good fire performance, and anti-aging performance.

Construction Method:

1,   Before use, dust, oil stains, and loose rust on the surface of the coated object should be cleaned, and the metal components should be rust-proofed.

2,   Stir the paint thoroughly. If it is too thick, add a special thinner to dilute it.

3,   During construction, brushing, rolling, and spraying can be used. Brush (spray) once every 6-8 hours, and wait for the surface to dry before the next brushing.

4,   The thickness of each coating layer ≤ 0.3mm.

5,   After the fire-retardant coating reaches the design thickness, dry for 48 hours and then apply the matching topcoat.

 

Packaging and Storage:

Packaged and stored according to national regulations. The storage environment should be dry, cool, and well-ventilated, avoiding high temperatures and keeping away from fire sources. The packaging container must be kept sealed. The effective storage period is 12 months.

 

Packaging Specifications: 25kg/ Sets
