DN-DJ Shield meets strict national fire coating standard GB 14907-2018 with reliable fire resistance up to 2 hours at 2.2mm film thickness. It rapidly expands into dense heat-insulating carbon foam under flame, stopping high-temperature transfer and preventing steel structural collapse to win critical evacuation time. With ≥0.15MPa strong bonding power and superior resistance to water, acid, alkali and thermal cycling, the coating stays intact without blistering, peeling or cracking for long-term durable fire protection on all primed steel substrates.
Unlike thick, ugly heavy fire mortars, DN-DJ forms a smooth, decorative thin layer perfect for visible steel structures in malls, stadiums and transit hubs. It supports spray, roller and brush application, with single spray pass reaching 5–8mm thickness and multi-coat intervals of only 6–8 hours to speed up construction progress. At just 1.0–1.2kg consumption per square meter per mm, it lowers overall material cost and shortens project timelines for industrial, commercial and transportation steel projects of all sizes.
Available in eco-friendly low-VOC water-based and durable solvent-based formulas to fit indoor and outdoor job sites. It delivers dual-function protection: reliable fire insulation plus anti-corrosion barrier for steel beams, columns, staircases and tunnel frames across stadiums, petrochemical plants, warehouses and subway tunnels. The water-based variant eliminates harsh solvent fumes for safer indoor construction, while consistent batch quality and simple surface prep workflow guarantee stable, predictable results for professional contractors every time.
