The Special Indoor Expansion Type Steel Structure Fireproof Coating (Water-Based) is a premium intumescent protective material designed for steel structures requiring high-level fire safety and environmental compatibility.
Product Introduction
The Special Indoor Expansion Type Steel Structure Fireproof Coating (Water-Based) is a premium intumescent protective material designed for steel structures requiring high-level fire safety and environmental compatibility. When subjected to fire, the coating rapidly expands and forms a dense, stable char layer that insulates the steel surface, significantly prolonging its load-bearing capacity. With its water-based formulation, the coating is safe, low in VOCs, and environmentally friendly, making it ideal for sensitive indoor projects where both performance and sustainability are critical.
Product Details
This special water-based coating is produced using advanced intumescent technology, flame-retardant additives, and eco-friendly resins. It comes ready-to-use, requiring only mixing before application. The coating can be applied by spraying, brushing, or rolling, producing a uniform finish that adheres firmly to steel substrates. Depending on project requirements, dry film thickness ranges from 1.5 mm to 3.0 mm, achieving fire-resistance ratings of 30–120 minutes. The smooth white or neutral finish can be left as is or overcoated with decorative paints.
Product Advantages
Superior Fire Resistance: Provides up to 2–3 hours of effective fire protection.
Eco-Friendly & Safe: Water-based, low-VOC, and odorless, suitable for indoor environments.
Enhanced Durability: Strong resistance to indoor humidity and general atmospheric conditions.
Lightweight Thin Film: Adds minimal weight to steel structures compared with cementitious coatings.
Aesthetic Finish: Smooth surface, easy to topcoat for design and architectural integration.
Simple Application: Compatible with conventional painting equipment, reducing labor costs.
