AG-CF03 Aerogel Intumescent Fireproof Coating for Steel Structure Combining nano-porous SiO₂ aerogel powder with ammonium polyphosphate, this coating forms a robust fire-resistant barrier. With a 2-hour fire rating at just 2mm thickness and 1.0MPa adhesion strength to metal surfaces, it sets a new standard for high-performance fire protection in steel structures across industries.
AG-CF03 is a high-performance industrial intumescent fireproof coating reinforced with nano silica aerogel technology. It is designed for steel structures, metal substrates, building projects, energy systems, petrochemical facilities, and advanced manufacturing applications requiring reliable fire resistance.
Self-produced nano-porous silica aerogel powder
High-efficiency intumescent flame-retardant system
Inorganic fire-resistant components
Through a specialized composite formulation, AG-CF03 achieves 2-hour fire resistance (F2.00) at only 2mm dry film thickness, tested according to GB 14907 standard.
This ultra-thin design provides effective fire protection while minimizing structural load and material consumption.
When exposed to high temperature or flame, AG-CF03 expands rapidly to form a dense carbonized char layer helps:
Reinforce the char layer structure
Improve thermal insulation performance
Reduce char collapse or cracking
Slow down heat transfer to the steel substrate
This aerogel-enhanced system improves the stability of the fire protection layer under prolonged fire exposure.
AG-CF03 provides 2 hour fire rating with only 2mm coating thickness.
Compared with conventional thick-film intumescent coatings, it reduces material usage and simplifies structural design.

Before and after fire exposure demonstrates the expansion behavior and char layer reinforcement of AG-CF03 under high temperature conditions.
Bonding strength: ≥1.0 MPa
The coating maintains stable adhesion to steel and aluminum substrates, helping reduce risks of peeling, cracking and delamination
Surface dry time: ≤4 hours
This improves construction efficiency and allows faster project completion.
After expansion, the coating forms a compact and reinforced char layer that helps maintain fire isolation performance during high-temperature exposure.
This provides valuable time for emergency response and fire control.
AG-CF03 is suitable for both building and industrial sectors.
It can be used independently or integrated with thermal insulation systems to form combined solutions for projects requiring both energy efficiency and fire protection.
