Indoor/outdoor intumescent steel structure fireproof coating is a water-based intumescent fireproof coating characterized by a thin coating layer and high adhesion. When applied to the surface of steel structures, this coating provides fireproofing and anti-corrosion protection; upon exposure to fire, the coating surface expands rapidly to form a uniform and dense fire insulation layer, thereby achieving fire protection for the steel structure.

This paint is divided into indoor and outdoor types; the outdoor paint has better waterproofing performance, is not easily peeled off, and has a longer service life.
