KD-WSP-FT JY-WB Outdoor Intumescent Fire Resistant Paint for Steel Structure

Description

JY-WB is a high-performance water-based intumescent paint for steel specifically designed for outdoor exposure and hydrocarbon fire protection. This environmentally friendly coating features a non-toxic, benzene-free formula that is VOC-compliant and safe for both applicators and the environment. With excellent fire resistance properties, it provides reliable protection for various structural steel profiles including H-beams in demanding industrial environments.

The coating’s fast-drying characteristics enable efficient spray application, significantly reducing project timelines while maintaining superior adhesion to properly prepared steel surfaces. Certified to GB14907-2018 standards and CCCF approved, JY-WB delivers exceptional performance in petroleum refineries, power plants, chemical processing facilities and other heavy industrial applications where hydrocarbon fire resistance is critical.

Key features:

✔ Fast-Drying & Easy Application – Spray-applied for high efficiency
✔ Eco-Friendly Formula – Non-toxic, solvent-free, and low-VOC
✔ 1-2.5 Hours Fire Rating – Complies with GB14907-2018 standard
✔ Weather-Resistant – Withstands harsh outdoor conditions
✔ CCCF Certified – Meets China’s stringent fire safety regulations

Ideal for: Industrial plants, power facilities, petrochemical plants, and H-beam structures.

Surface Preparation Guidelines for Intumescent Paint Application on Steel Structures

1. Primer System Requirements
   After sandblasting treatment, steel surfaces must be coated with a compatible anti-corrosion primer system. We recommend using the “Jinyu” brand epoxy zinc-rich primer combined with epoxy micaceous iron oxide intermediate coat to ensure proper adhesion with the intumescent paint for steel. Both primer and intermediate coats must form a continuous, defect-free film to completely seal the substrate, otherwise it may lead to delamination of the fireproof coating and substrate corrosion.

2. Alternative Primer Compatibility Testing
   When using other primer systems, compatibility testing must be conducted either by certified laboratories or through on-site brush-out tests to verify proper bonding with the intumescent fireproof coating for steel structures.

3. Application Restrictions
   The intumescent coating must never be applied directly onto:
   ✓ Unprimed steel surfaces
   ✓ Galvanized coatings
   Direct application may cause coating failure and accelerated steel corrosion.

4. Pre-Application Inspection
   Prior to applying the hydrocarbon fire resistant intumescent paint, thoroughly inspect for:
   ✓ Complete primer coverage
   ✓ Surface contaminants (dust, oil residues)
   ✓ Structural defects (cracks, inadequate welds)
   Application should only proceed after passing all inspections.

Application Guide

1. Mixing: Stir with electric mixer; add ≤5% water if needed.

2. Spraying:

   • Apply in crosshatch layers (1–2mm per pass).

   • First layer: ≤1.5mm thickness.

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

3. Environment:

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

   • Humidity: ≤80%.

4. Reinforcement: Use fiberglass mesh for critical areas.

Storage & Transport

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

• Shelf life: 6 months (avoid moisture).

  Project Case: Hainan Ocean Flower Island Fireproof Coating Application

  The Hainan Ocean Flower Island development (2018) utilized WeB and BTCB-1 fireproof coatings across 107,000 square meters of structural steel in high-humidity coastal conditions. Our solutions provided 120-minute fire resistance for resort complex structures while meeting GB 14907-2018 standards, with specialized anti-corrosion properties to withstand tropical marine environments. This large-scale tourism project demonstrates our capability to deliver aesthetic and durable fire protection for island mega-developments.
