FS703 NULLIFIRE Black Fire Sealant 310ml is a neutral silicone sealant that cures with moisture in the air to quickly form a flexible and durable seal. It has the SNJF Façade and Glazing labels as well as the Efectis test report for 240 minutes No. EFR-14-001723 for expansion joints.
The FS703 sealant is used for creating fire-resistant joints: in construction between concrete masonry elements, cellular concrete, for sealing fire-resistant glazing, for sealing oculi, and in the construction of fire-resistant works (wall penetration of pipes, air ducts). FS703 can be used alone or in combination with special backing materials that are themselves classified as non-flammable (NEC+ Nullifire fire stop strip, Altofeu rock wool, artificial mineral fibre joints).
