FS709 HP Intumescent Sealant 310ml

Nullifire FS709 HP Intumescent Sealant is a high expansion/pressure exerting, graphite intumescent sealant. FS709 expands when exposed to fire, reinstating the fire performance of compartment walls and floors that have been penetrated. FS709 has been tested to provide up to 4 hours of fire resistance by closing off pipe penetrations in the event of a fire, eliminating the need for pipe closers or wrap systems. Our excellent formulation also incorporates a unique identification property offering architects, specifiers, main contractors, and applicators guaranteed traceability of product on-site. Optifire technology is activated by exposing the product's surface to a UV light source, which offers easy and instant product identification.
