KD-NSP-FP-SB-3 Cat Tahan Api Intumescent Dalam Ruangan untuk Struktur Baja

Deskripsi

Deskripsi Produk:

SB-3 represents our premium indoor fire resistant paint for steel, an intumescent coating system specifically engineered to protect against standard cellulosic fires (Class A). This water-based fireproof coating offers an eco-friendly solution with zero VOCs, non-toxic formulation, and minimal environmental impact. With a proven track record since its 1994 launch, this steel structure fire protection coating delivers exceptional durability and stability, earning recognition as a National Key New Product in 1995. Ideal for diverse applications including residential apartments, commercial high-rises, industrial facilities, airports, and critical infrastructure projects, it provides reliable fire protection for indoor steel structures – particularly effective for large-span steel frameworks in both industrial and civil engineering applications.

Fire Resistant Paint Substrate Preparation:

• Surface Preparation & Coating Requirements:
  After sandblasting the steel surface, apply a compatible anti-corrosion primer and intermediate coating system. We recommend using the “Jinyu” brand epoxy zinc-rich primer + epoxy mica iron oxide intermediate coating, which ensures excellent adhesion. Both the primer and intermediate coat must be smooth, undamaged, and fully seal the substrate. Failure to do so may cause indoor fire resistant paint for steel to delaminate or lead to substrate corrosion.
• Alternative Primer Compatibility Testing:
  If other types of primers are used, compatibility tests must be conducted. This can be done through professional lab testing (adhesion and chemical resistance tests) or on-site trial applications.
• Prohibited Practices:
  Do not apply fireproof coatings for steel structures directly onto unprotected substrates or galvanized surfaces. This can cause corrosion and adhesion failure of the steel fire protection coating.
• Pre-Installation Inspection:
  Before applying intumescent paint for steel beams, thoroughly inspect the steel components for:
  • Proper rust-proof primer application
  • Dust, oil, or contaminants
  • Cracks or weak welds
    Only proceed with fire-resistant coatings for industrial steel after confirming all requirements are met.

2. Spray application: 1-2mm per layer (max 1.5mm first layer)

3. Maintain 12+ hours between coats

4. Optimal conditions: 15-30°C, ≤80% humidity

Penyimpanan:

• Keep in dry, ventilated areas (≥5°C)

• 6-month shelf life

Project Case: International Economic & Trade Exchange Center Fireproof Coating Application

The International Economic & Trade Exchange Center (2020-2021) utilized STI-A and SB-3 fireproof coatings across its 207-meter steel structures, providing 120-minute fire resistance for the venue’s large-span conference halls. Our solutions met GB 50016-2014 standards while maintaining architectural transparency requirements, demonstrating effective fire safety integration for this high-profile diplomatic and commercial hub.

Project Case: Grand Canal Museum Fireproof Coating Application

The Grand Canal Museum project (2020-2021) implemented STI-A and SB-3 fireproof coatings across 13,500 square meters of structural steel, achieving 120-minute fire resistance for critical exhibition spaces while meeting both GB 50016-2014 safety standards and GB/T 33215-2016 cultural heritage protection requirements. Our solutions provided seamless fire protection for the museum’s large-span glass-steel hybrid structure, ensuring unobtrusive safety for this UNESCO-recognized cultural landmark.
