Cementitious fire protection is typically applied using specialized spray equipment to safeguard structural steel or concrete against the damaging effects of fire, providing a designated period of fire resistance.
Gypsum-based sprays, often categorized as cementitious, can be used indoors similarly to Portland cement-based sprays. However, most gypsum formulations are not recommended for external or semi-external environments due to limited moisture resistance.
Gypsum-based cementitious fireproofing coatings offer excellent physical properties for interior and architectural applications, delivering up to four hours of fire protection.
Intumescent fire-resistant coatings are protective finishes, similar to paint, applied to structural steel components. These coatings may come in various forms, including paints, mastics, or foam composites. Once applied, their final thickness typically ranges from 0.03 inches to 0.50 inches.
The primary function of intumescent coatings is to act as an insulating barrier, protecting steel from high temperatures during a fire. By delaying heat transfer, they help maintain the structural integrity of the steel under fire conditions. Intumescent coatings can offer up to 120 minutes of fire protection, depending on the application and formulation
NAFFCO PSV-ISW-180
NAFFCO PSV-ISW-180 is a white thin film water-borne intumescent coating for the fire protection of internal structural steelwork in combination with suitable for the topcoat.
NAFFCO PSV-ISW-180 should apply onto a clean, undamaged, dry and primed steel surfaces only.
NAFFCO PSV-ISS-120
NAFFCO PSV-ISS-120 is a white single pack thin film coating that foams up under the effect of fire or heat (intumescent) to form an insulating layer. Fire protection system for structural steel is available in two different grades for internal and external use.
