The Outdoor Expansion Type Steel Structure Fireproof Coating (Solvent Type) is a high-performance intumescent coating engineered to protect exterior steel structures from fire hazards while resisting harsh outdoor environments.
Product Introduction
The Outdoor Expansion Type Steel Structure Fireproof Coating (Solvent Type) is a high-performance intumescent coating engineered to protect exterior steel structures from fire hazards while resisting harsh outdoor environments. When exposed to flames or high temperatures, the coating expands into a stable, carbonized char layer that insulates the steel, extending its structural integrity and providing valuable time for evacuation and firefighting. With its solvent-based formulation, this product offers superior curing speed, strong adhesion, and enhanced durability, making it ideal for demanding outdoor projects requiring long-term fire and weather protection.
Product Details
This coating is formulated with advanced resins, flame-retardant agents, and weather-resistant additives. It can be applied by spraying, brushing, or rolling, forming a smooth and uniform film that adheres tightly to steel surfaces. Designed for outdoor use, it resists ultraviolet (UV) radiation, rain, and temperature variations. The dry film thickness is determined by the fire rating requirements, typically ranging from 1.5 mm to 4.0 mm for 30–120 minutes of fire protection. To maximize performance, it is applied over an anti-corrosion primer and finished with a protective topcoat.
Product Advantages
Strong Fire Resistance: Provides up to 2–3 hours of certified fire protection.
Superior Durability: Excellent resistance to UV, rain, and long-term outdoor aging.
Fast Curing: Cures faster than water-based coatings, even in low-temperature or humid conditions.
Excellent Adhesion: Bonds firmly to primers and topcoats, preventing cracking or peeling.
Decorative & Protective Finish: Compatible with weather-resistant paints for long-lasting aesthetic appeal.
Reliable Performance: Tested to meet international fireproofing and construction standards.

FAQ
Q1: How long is the shelf life?
A1: 12 months when stored unopened in a cool, ventilated environment.
Q2: Is a primer necessary before applying this coating?
A2: Yes. A corrosion-resistant primer is essential for outdoor steel surfaces.
Q3: Do I need a topcoat?
A3: Yes. A UV- and weather-resistant topcoat is strongly recommended for long-term outdoor durability.
Q4: What fire ratings can it achieve?
A4: 30, 60, 90, or 120 minutes depending on the applied thickness.
Q5: What is the difference from the water-based type?
A5: Solvent-based coatings cure faster, bond stronger, and perform better in harsh outdoor climates, while water-based options are more eco-friendly.
