FS709 Intumescent Mastic

FS709 is a high-pressure, intumescent mastic that expands when exposed to fire, protecting penetrations including cables, cable bundles, cable trays and plastic and metal pipes.

FS709 is designed to seal gaps and penetrations in partition walls and floors to provide up to 4 hours of fire resistance.

This product has been formulated in such a way that, in the event of a fire, it seals plastic pipe penetrations in the areas where it is applied, eliminating the need for pipe collar or wrap systems.
