Gypsum-based non-expansive steel structure fire-resistant coating

This fire-resistant coating is primarily based on gypsum, utilizing a powder mixture of inorganic lightweight insulating materials and fibers. Compared to cement-based fire-resistant coatings, the gypsum-based option is environmentally friendly with low-carbon and energy-saving raw materials. It is lightweight, has a small density, and offers some decorative effects, with a visually appealing, non-bulging, and non-cracking finish. Additionally, it has strong adhesion, good deformation resistance, and excellent fire resistance. It provides up to 4 hours of fire protection against fiber and hydrocarbon fires. The finished product is less prone to cracking and peeling, breaking through the bottleneck of layered and divided construction methods for cement-based coatings. It can be applied in a single spray-coating operation without the need for nails or mesh. Suitable for indoor steel structures, corrugated steel sheets, and precast concrete components. The product includes models: GT-NSF-Fp1.50-YXLB-SG, GT-NSF-Fp2.00-YXLB-SG, GT-NSF-Fp2.50-YXLB-SG, GT-NSF-Fp3.00-YXLB-SG, GT-NSF-Fp3.00-YXLB-SG (4h).

The paint features:

Structural load lightness

Ease and speed of construction: 15-minute curing technology, fast construction speed, saves labor.

Cost-effectiveness: Spray-painting process for one-time molding;

Construction quality: Gypsum-based materials offer excellent flexibility, strong resistance to deformation, and do not crack, hollow, sag, or peel off.

Green Environmental Protection, Zero Pollution: Inorganic materials free of asbestos, benzene, and glass fiber substances; VOC content (volatile organic compounds) and heavy metal content are both zero.

Fire resistance longevity: Neutral material, does not promote steel corrosion.

Stable refractory properties.

Superior soundproofing performance: Offers certain soundproofing effects.

Versatile decorative options:可直接批腻子、刷各类面漆； (Note: The original text "多种多样装饰性" was not provided, so it was omitted from the translation.)

Corrosion Protection Longevity: Gypsum-based fire-resistant coatings can provide corrosion protective finishes for steel structures, aiding in enhancing the lifespan of corrosion-inhibitive paints to over 20 years and more.

Installation Instructions:

Mix the paint thoroughly with water at a 1:1 ratio.

Open or close the spray gun air valve, move the spray gun, turn on the spraying machine, and prepare for spraying. Keep the spray gun 30-50 cm away from the component, with the nozzle maintaining a roughly perpendicular angle to the base surface, and move the spray gun parallel to the surface of the base material.

When spraying the exposed corners of components, start from the tip, spraying vertically from top to bottom or from left to right onto the base surface, followed by horizontal spraying. For the concealed corners, begin by spraying vertically from top to bottom from one side of the corner, then move horizontally to spray.

When spraying vertically, keep the nozzle further from the top angle; when spraying the bottom of the spray beam, avoid an overly steep angle for the spray gun.

Apply continuous spraying until the desired coating thickness is achieved. For a smooth surface, simply level it off. 6. During the application process, the operator should use a thickness gauge to check the coating thickness until it meets the requirements, then stop spraying. (Note: If the paint fails to adhere, it may be due to too much mixing water, improper thickness control, or an unclean substrate.)

In the event of an interruption in production (over 1 hour) or upon completion, the mixing and spraying equipment should be cleaned immediately to prevent damage due to paint solidification.
