KD-WRP-FP-WCB Outdoor Intumescent Steel Structure Fire Resistant Paint

Description

Product Description

WCB Outdoor Intumescent Fire Resistant Paint for Steel Structures is our premium solvent-based fire protection system, specially formulated to withstand hydrocarbon fires while providing excellent resistance to cellulosic fires. This high-performance fire intumescent paint features a thin-film application with strong adhesion, allowing for versatile application methods including spraying, brushing, and rolling. The complete protection system consists of a fireproof base coat combined with a durable, corrosion-resistant topcoat, delivering exceptional weather resistance and long-term performance for outdoor steel structures. Certified to GB14907-2018 standards with 1.5-2 hour fire ratings and CCCF certification, it’s ideal for protecting I-beams and H-beams in industrial plants, stadiums, airports, TV towers, and petrochemical facilities. With its proven technology and field performance, WCB offers reliable, long-lasting fire resistant paint solutions for critical steel structures.

✔ Corrosion & Weather Resistance – Includes decorative topcoat for durability
✔ CCCF Certified – Complies with China’s fire safety regulations

Ideal for: Industrial plants, airports, TV towers, stadiums, and petrochemical facilities.

Certifications & Test Data

• GB14907-2018 certified (1.5h, 2.0h ratings)

• CCCF Fire Product Certification

• Low thermal conductivity (tested for heat insulation)

Surface Preparation Requirements for Fireproof Coating Application

1. Primer Application

   • Steel surfaces must be sandblasted and coated with a compatible anti-corrosion primer system. We recommend using the “Jinyu” brand epoxy zinc-rich primer + epoxy micaceous iron oxide intermediate coat for optimal adhesion.

   • The primer and intermediate coats must form a smooth, unbroken protective layer to completely seal the substrate. Failure to do so may lead to coating delamination and substrate corrosion.

2. Alternative Primer Compatibility

   • If using other primer types, compatibility testing must be conducted by qualified agencies or through on-site brush-out tests to ensure proper bonding with the fire intumescent paint.

3. Surface Restrictions

   • Never apply intumescent coating for steel directly onto:
     ✓ Unprimed steel surfaces
     ✓ Galvanized layers

   • Direct application may cause coating failure and accelerated corrosion.

4. Pre-Application Inspection

   • Thoroughly inspect steel components for:
     ✓ Complete primer coverage
     ✓ Surface contaminants (dust, oil, etc.)
     ✓ Structural defects (cracks, poor welds)

   • Proceed with fire resistant paint application only after passing inspection.

Application Guide

1. Mixing: Stir thoroughly; add ≤5% approved thinner if needed.

2. Coating:

   • Apply in crosshatch layers (0.2mm dry film/layer).

   • Interval: 12+ hours between coats (adjust for temperature).

3. Environment:

   • Temperature: 15–30°C (limits: 5–35°C).

   • Humidity: ≤80%.

4. Curing: Requires 1-month curing post-application.

Storage & Transport

• Store in dry, shaded areas (≥5°C).

• Shelf life: 12 months.

• Project Case: Velana International Airport Expansion, Maldives (2020-2021)

  The Velana International Airport expansion project implemented SB-2, BTCB-1, and WCB fireproof coatings across terminal steel structures, achieving 180-minute fire resistance (ICAO Annex 14 standards) for critical load-bearing components in high-humidity coastal conditions. Our corrosion-resistant solutions withstood salt spray exposure while meeting both international aviation safety requirements and the Maldives’ stringent environmental regulations for island infrastructure.

  

• Project Case: Sichuan Yongxiang Polysilicon Fireproof Coating Application

  The Sichuan Yongxiang Polysilicon facility (2021) implemented WOB and STI-C fireproof coatings across 117 meters of critical steel structures in high-temperature production areas. Our solutions provided 120-minute fire resistance for silicon reactor supports, meeting GB 50016-2014 standards while withstanding corrosive chemical vapors unique to polysilicon manufacturing. This project demonstrates our expertise in safeguarding specialized industrial processes through tailored fire protection systems.
