Indoor Non-Intumescent Fireproof Coating ~ Indoor Non-Intumescent Steel Structure Fireproof Coating (Paint Sales Manager Sun: 152^0825^6966) Available for sales in Sichuan, Chengdu, Yunnan, Chongqing, Guizhou, and other regions; Non-intumescent characteristics: Unlike intumescent coatings, this type of coating does not foam to form an insulating layer under high temperatures. Instead, it relies on its inherent low thermal conductivity (e.g., components like vermiculite, ceramic fibers) to form a dense thermal barrier, preventing heat transfer to steel components. Fire resistance limit: Typically up to 2-3 hours (e.g., thickness of 5-10mm).
Application Scenarios
Large public buildings: Steel roof trusses of stadiums, airport terminals.
Industrial facilities: Steel frameworks of petrochemical plants (requires use with anti-corrosion primer).
Concealed structures: Areas with high fire protection requirements but no need for decoration (e.g., steel beams within ceilings).
Key Construction Points
Substrate treatment: Must sandblast to remove rust to Sa2.5 grade, apply epoxy zinc-rich primer for anti-corrosion.
Coating process: Multiple spray layers (single layer ≤3mm), total thickness must strictly follow design (tolerance ±0.5mm).
Environmental requirements: Construction temperature 5-35°C, humidity ≤85%, avoid condensation.
Comparison with Other Fireproof Coatings
| Characteristics | Non-Intumescent | Intumescent |
|---|---|---|
| Fire resistance principle | Physical insulation | Chemical expansion (char layer) |
| Coating thickness | Thicker (5-50mm) | Thinner (1-3mm) |
| Decorative quality | Poorer (often requires decorative topcoat) | Better (color adjustable) |
| Suitable environment | High humidity, concealed areas | Dry, exposed steel structures |
