- Product Description
Protect Your Steel Structures with Professional Fire Safety Solutions
When protecting steel buildings in factories with high temperatures, you need an answer you can count on. Solvent fire retardant coating for steel structure from Henan Banggu Fire Technology provides high-level fire protection that has been demonstrated to work. Our non-intumescent coating makes a thick layer that keeps heat out and can withstand temperatures up to 1500℃ for at least 2.5 hours. We've helped many factories, power plants, and heavy-duty plants improve their fire safety with our more than 30 years of experience making coatings, which we got from Henan Tiantan Anti-corrosion Co., Ltd. Our layer has a long service life of more than 12 years, strong adhesion, and resistance to rust, making it perfect for your long-term project needs.
Why Choose Our Solvent-Based Fire Retardant Coating?
Fast-Drying and High-Efficiency Application
On building projects, time is money. Our solvent fire retardant covering for steel structures dries quickly, which cuts the time it takes to finish your job by a lot. It can be sprayed on or troweled on, which makes it perfect for building on big areas of land. It only takes 0.5 to 1 hour for the surface to dry, and 12 to 24 hours for the whole thing to fix.
Fire Protection Performance
During fires, your steel buildings are in great danger. Our layer makes a thick shield that keeps heat out and keeps steel from changing shape and losing its ability to hold weight at high temperatures. It was made to work in places like power plants, boilers, and factories where high heat is a constant worry.
Excellent Adhesion and Durability
It doesn't matter how well a coating works if it peels or cracks. Our recipe guarantees a bonded strength of at least 0.15 MPa and a compression strength of at least 0.3 MPa. Even after 72 hours of being wet, the layer doesn't crack or peel. You'll be safe and protected for a long time.
Lightweight and Cost-Effective
Coatings that are too heavy add extra weight to the structure. Our approach keeps extra weight to a minimum while increasing fire protection to the highest level. A thin layer width uses less material, so your project costs will stay low without lowering safety standards.

Where You Can Use It?
Our solvent fire retardant coating for steel structure is perfect for indoor applications requiring robust fire protection:
- Industrial manufacturing plants
- Power generation facilities
- Steel beams and columns
- Steel trusses and space frames
- Heavy-duty industrial environments
Important Note: This product is designed for indoor use only. For outdoor applications exposed to UV and weather conditions for more than 5 years, you'll need an additional UV/weather-resistant protective layer.
Application Made Simple
Before You Start
- Ensure ambient temperature is between 5°C and 40°C
- Keep relative humidity ≤85%
- Substrate temperature should be ≥3°C above dew point
- Avoid application during rain, fog, or high winds
- Ensure proper rust prevention treatment on substrate
Application Methods
Spraying (Recommended for Large Areas)
- High efficiency and smooth finish
- Ideal for industrial-scale projects
Brushing or Rolling
- Suitable for smaller areas or touch-ups
- Easy manual application
Coverage Reference
Theoretical coverage is approximately 1.2–1.5 kg/m² per mm of thickness. Your actual coverage depends on the designed fire-resistant thickness for your specific project requirements.

FAQ
Q1: What distinguishes solvent-based and water-based coatings?
A: Solvent-based coatings dry faster, adhere better, resist water, and harden. They're great for interior tasks that need strength, weather resistance, and fast drying. Environmentally friendly water-based solutions dry slowly but have less odour.
Q2: Does it meet fire codes?
A: Our coating meets GB 14907-2018 "Fireproof Coatings for Steel Structures." National fire protection product test reports qualify it for fire safety inspections and acceptance.
Q3: How long does it take between coats to dry?
A: Surface dries in 0.5–1 hour. The full cure takes 12–24 hours. At least 4 hours should pass between coatings (longer in colder conditions).
Q4: Can I topcoat for aesthetics?
A: Absolutely. Apply appropriate solvent- or water-based topcoats after drying. This will improve stain resistance and aesthetics without fire resistance. Custom colours are possible, although white and light grey are standard.

Q5: How should I apply safely?
A: Workspace ventilation is essential. Ban smoking, open fires, and static electricity. Make fire extinguishers available. Workers need masks, goggles, and gloves. Despite solvent vapours during application, the coating is non-toxic and nontoxic after drying.
