Product Description
Water-Based Intumescent Fireproof Coating for Steel Structures
Product Overview
Ultra-thin steel structure fireproof coatings are specialized intumescent paint-like materials applied to steel structural surfaces to provide fire resistance. When exposed to high temperatures, these coatings expand and char, creating an insulating layer that protects the underlying steel from rapid heating and maintains structural integrity during fire events.
Key Features & Benefits
- Thin application (0.5-3 mm) for aesthetic appeal and space efficiency
- Lightweight solution adding minimal weight to structures
- Strong adhesion with bond strength ≥0.39 MPa
- Quick drying time (≤5 hours surface dry)
- Excellent water resistance and thermal cycling performance
