KD-WSP-FT JY-WB Pintura ignífuga intumescente de exterior para estructuras de acero

Descripción

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.

Surface Preparation Guidelines for Intumescent Paint Application on Steel Structures

1. Primer Requisitos del sistema
   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. Pruebas de compatibilidad de imprimaciones alternativas
   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. Restricciones de aplicación
   The intumescent coating must never be applied directly onto:
   ✓ Superficies de acero sin imprimar
   ✓ Recubrimientos galvanizados
   Direct application may cause coating failure and accelerated steel corrosion.

4. Inspección previa a la solicitud
   Prior to applying the hydrocarbon fire resistant intumescent paint, thoroughly inspect for:
   ✓ Cobertura completa del cebador
   ✓ Contaminantes superficiales (polvo, residuos de aceite).
   ✓ Defectos estructurales (grietas, soldaduras inadecuadas).
   Application should only proceed after passing all inspections.

  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.
