Service Life
Design life of structure
Environment
Interior and exterior (with topcoat for exterior)
Layers
3 coat system
FireSeal intumescent fire-retardant coating providing passive fire protection for structural steel. Expands 40-50 times when exposed to fire, forming an insulating carbon char layer that protects steel from reaching critical temperature.
