Cementitious fire protection is normally spray
applied using specialist equipment to protect
structural steel or concrete from the effects
of fire for a nominal fire resistance period.
Gypsum based sprays are sometimes considered
as Cementitious and may be used internally in the same way as Portland cement
sprays, though most gypsums are not suitable for external or semi external
locations.
The gypsum based fireproofing Cementitious paint has excellent physical properties for interior or architectural uses and Cementitious paint can give up to 4 hours fire protection. NAFFCO has very recently launched a new Cementitious Paint, which is vermiculite and gypsum based and provides very efficient fire resistance up to 240 minutes depending on the thickness
NAFFCO PSV-C-1 is used for the interior and exterior steel structures of buildings with excellent adhesion. NAFFCO PSV-C-1 is formulated with materials such as cement, vermiculite, fibre (asbestos-free) and special inorganic fire protection materials, not only to keep the intensity of cement rigid & also with the tough characteristics of interlaced fibre like a net, its physical properties are better than the similar products available in the market.
NAFFCO PSV-C-2 Spray-Applied Fire Resistive Material is used in building construction to have excellent adhesion on steel substrates. NAFFCO PSV-C-2 is formulated with materials such as cement, vermiculite, fibre (asbestos-free) and some other organic and inorganic materials, where it does not only show the characteristic of steel strength of concrete, but also the toughness and flexibility of the cross-stitched network of fibre.
NAFFCO PSV-C-HC-100 based on cement, vermiculite and special high chemical resistant fibre, and contains no asbestos. It is used on exterior and interior steel structures of the building. It has rigid and tough characteristics. It resists a rapidly rising temperature and polluted environment and has the best fire-resistive coating for petrochemicals plants and general industrial equipment.
NAFFCO PSV-C-3 is a lightweight spray or trowel applied, single package factory controlled premix based on vermiculite and gypsum which applicable for internal use. NAFFCO PSV-C-3 provides very efficient fire resistance from 15 to 240 minutes depending on the thickness. It can be used for Concrete structural elements, Structural steel and Load-bearing flat concrete profiles sheet composite elements.
