HP Intumescent Sealant
FS709 HP is a high expansion/pressure exerting, graphite intumescent sealant that expands when exposed to fire, reinstating the fire performance of compartment walls and floors which have been penetrated with services.
FS709 can be used on flexible walls & rigid walls (100 mm or wider), rigid floors (150 mm or wider), and also with FB750 Intubatt Coated Batts.
FS709 is designed to close off gaps and penetrations in compartment walls and floors, to provide up to 4 hours fire resistance. This product has been formulated to close off combustible pipe penetrations in the event of a fire, negating the need for pipe closers or wrap systems. FS709 has been tested with the following service penetrations: combustible pipes up to 125 mm (ABS, PE, PP, HDPE, PVC, PEX...) insulated non-combustible pipes up to 160 mm ; pipe insulation types: nytrile rubber, glass fibre, rock fibre up to 60 mm insulation wall thickness individual or groups of cables, perforated & non-perforated cable trays, cable ladders, cable baskets (up to 500 mm), cable bundles (up to 100 mm) For use in dry internal conditions only. For other conditions, such as high humidity, contact Technical Services.
Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest documents are downloaded prior to every project commencement.
